Eclipse 4.5 SR2 released!

26 February 2016

Another year, another SR release; the Eclipse organization released maintenance release two of Eclipse 4.5 (aka, MARS.2, aka Eclipse 4.5.2) today.

The release has been done with little fanfare. There’s no notion of this event anywhere on the homepage. On the top of the page at the moment of writing is the Eclipse Foundation + Google Summer of Code and the fact that the EclipseCon 2016 starts March 7. The actual IDE that is Eclipse is not mentioned. Main releases typically are, but SR releases aren’t, or at least not right away. Last year we saw the event being put on the homepage after about 5 days.

As it appears, there were 95 bugs fixed for this release in the core of Eclipse.

Among others a somewhat older but high profile OS X bug is fixed involving a nasty NPE and an obscure one where Eclipse would actually delete code.

Furthermore the usual assortment of totally weird bugs where fixed, the ones even the most experienced developers have hardly any idea about what they could mean. Stuff like ClassCastException in Theme$1.propertyChange.

This time around the good people from the WTP project did not feel like posting about the SR2 event on their homepage. Fiddling with the handy bugzilla URLs revealed a list of 22 bugs that are likely to be fixed in WTP 3.7.2, the version that should be the one that’s bundled with Eclipse 4.5.2.

Among the highlights of bugs that WTP 3.7.2 fixed is a fix for the fact the pom.xml did not match a Most other fixes focused on solving null pointer exceptions. No less than 9 different ones of these were solved, including the dreaded NullPointerException in ParameterGuesser$VariableCollector.collect. Interesting to note is that all of these were reported via the automated error reporting that was introduced with Eclipse 4.5. Next to null pointer exceptions, a couple of array index out of bounds exceptions where fixed as well.

Following the trend, community reporting is even lower than last year. This year there’s really no reporting at all. But it has only been released today, so maybe a few outlets will pick it up in the following days.

It remains a fact, year after year, that SR releases apparently aren’t that exciting. But the lack of announcements about them and the silent releases of what should really be one of the most important products that the Eclipse organization delivers remains a curious thing.

Luckily the milestones for the next Eclipse, code named Neon (4.6), do get some more attention.

Mysterious Eclipse Luna update is SR1a

15 January 2015

Two days back I noticed Eclipse had a mysterious update available; Eclipse IDE for Java EE Developers, version with id “epp.package.jee”:


Of course there was no info on what this update was about and Googling for it yielded no results. Googling again for it today gave a single hit:

Looking at the URL revealed that “” is the alternative universe version for what’s otherwise known as “Luna SR1a”. Googling for the latter gave some more results, particularly the following one:

Eclipse Ships Luna SR1a Git Security Release

A bit out of character, but the Eclipse organization even linked to this from their homepage!

Why it’s so difficult for Eclipse to show a description for their updates is still a small mystery, but at least the mystery of what “” is about is now solved 😉

Eclipse 4.4 SR1 once again completely silently released

29 September 2014

Another year, another SR1 release, another deafining amount of silence; the Eclipse organization released maintance release one of Eclipse 4.4 three days ago.

As usual, there’s no notion of this event anywhere on the homepage. What counts this time is the Eclipse Newsletter about Project Quality and the fact that LocationTech has announced the 2014 Tour. The actual IDE that is Eclipse doesn’t seem to be that important.

As it appears, there were 131 bugs fixed for this release in the core of Eclipse.

Among others a high profile bug is fixed where Eclipse generated a bad class file and another bug where JSR 45 support (JSP debugging among others) was completely broken.

Furthermore several bugs related to Java 8 were fixed. As Eclipse uses its own compiler (JDT), supporting new language features is always extra difficult for Eclipse as compared to other IDEs that just use javac.

Eclipse 4.4 SR1 fixed some nasty issues with lambda type inference (and another one), deserialization, bridge methods, and explicit null-annotations.

Unfortunately, even with the focus on Java 8 fixes, a very basic and known type inference bug is still in Eclipse 4.4.1, as found out by my co-worker Jan Beernink:


This time around even the good people from the WTP project did not feel like posting about the SR1 event on their homepage. Fiddling with the friendly bugzilla URLs revealed a list of 32 bugs that are likely to be fixed in WTP 3.6.1, the version that should be the one that’s bundled with Eclipse 4.4.1.

Among the highlights of bugs that WTP 3.6.1 fixed is a fix for that fact the JSF EL validation is too strict and that when using the famous “Run on Server” feature, a wrong URL mapping is used.

Following the trend, community reporting is even lower than last year. This year there’s virtually no reporting at all. There’s a lone post from an Eclipse vendor, and that seems to be it.

Unfortunately Eclipse 4.4.1 also introduced a major new bug, one that’s appears right away when you startup a completely clean freshly downloaded instance:

java.lang.ClassCastException: org.eclipse.osgi.internal.framework.EquinoxConfiguration$1 cannot be cast to java.lang.String
	at org.eclipse.m2e.logback.configuration.LogHelper.logJavaProperties(
	at org.eclipse.m2e.logback.configuration.LogPlugin.loadConfiguration(
	at org.eclipse.m2e.logback.configuration.LogPlugin.configureLogback(
	at org.eclipse.m2e.logback.configuration.LogPlugin.access$2(
	at org.eclipse.m2e.logback.configuration.LogPlugin$
	at java.util.TimerThread.mainLoop(

It seems clear that SR releases aren’t that exciting, but the complete lack of attention to them and the completely silent releases of what should be the most important product that the Eclipse organization delivers remains a curious thing.


Maybe after reading this article (who knows ;)), but a few days later the Eclipse organisation did finally post about the release event, and the following appeared on the homepage:

Eclipse Luna SR1 Now Available
The SR1 release of the Eclipse Luna release train is now available for download.

Eclipse 4.3 SR1 again silently released!

28 September 2013

Again rather silently, the Eclipse organization yesterday released the first maintenance release of Eclipse 4.3; Eclipse 4.3.1 aka Eclipse Kepler SR1.

Surprisingly (or maybe not), this event again isn’t noted on the main homepage at or at the recent activity tracker. There also don’t seem to be any release notes, like the ones we had for the 4.3 release.

It seems these days the Eclipse home page is about anything and nothing except the thing we most closely associate with the term “Eclipse”; the Eclipse IDE. Seemingly the IDE itself is by far not as important as “Concierge Creation Review Scheduled” and “Web-based BPM with Stardust”.

Once again, fiddling with Bugzilla gave me a list of 112 bugs that are fixed in core packages.

Hopefully this fix will remedy the random crashes I’ve experienced in Ubuntu 13.04, but I’m not holding my breath.

The good people at the WTP project did feel like posting about this event on their homepage with a link and short description to the 3.5.1 release of WTP. Again, the new and noteworthy keeps pointing to the previous release, but there’s a list of 51 fixed bugs available.

Community reporting seems to have reached a historically low. There’s one enthusiastic user who created a rather minimalistic forum post about it, and that’s pretty much it. Maybe a few lone tweets, but nothing major.

Is the community and the Eclipse organization loosing interesting in Eclipse, or is it just that SR releases aren’t that exciting?

Eclipse 4.2 SR1 silently released!

30 September 2012

Rather silently, the Eclipse organization 2 days ago released the first maintenance release of Eclipse 4.2; Eclipse 4.2.1 aka Eclipse Juno SR1.

Surprisingly, this event isn’t noted on the main homepage at or at the recent activity tracker. There also don’t seem to be any release notes, like the ones we had for the 4.2 release.

Fiddling with Bugzilla gave me a list of 80 bugs that are fixed in core packages.

This time around, the WTP project did feel obliged to post about this event on their homepage. Following the Eclipse 4.2.1 release train, WTP was upgraded from 3.4.0 to 3.4.1. The famous “new and noteworthy” of WTP 3.4.1 unfortunately still points to the previous 3.4.0 release, but there is a list of fixed bugs available that luckily does point to the right version.

Community reporting about 4.2 SR1 has been equally underwhelming, although just today Steffen Schäfer posted about this release focussing on the new JGit/Git 2.1 versions. Besides him there’s a Chinese post about 4.2.1, which just says the following:

To enhance performance, fixed many bug and the export of war with java source code bug fixes!

Is it perhaps so that with the increasing size, complexity and sheer number of plug-ins and projects on, the one thing that we all simply call “Eclipse” becomes more and more difficult to identify as a specific product on that site and as such harder to report about?

And what about the adoption of the Eclipse 4.2 platform? There has been much debate recently about the abysmal performance of the new platform. Is SR1 a step in the right direction, or do we have to wait for 4.2 SR2, or possibly even 4.3?

IntelliJ – The IDE I wanted to love

27 June 2009

In the Java market we have a plethora of ide’s to choose from. The one I am most familiar with and also see used most often is Eclipse. Everyone knows Eclipse of course. Eclipse is not without its faults. So its natural to look around every so often. Eclipse is my baseline. At this point we arrive at IntelliJ. IntelliJ is another well known ide. I have heard IntelliJ described as the only ide for java developers, the ide that wil increase productivity 10-100 times. Its a commercial product which means you can have a reasonable expectation of stability, customer support and all the nifty tooling you would expect in Eclipse or any other ide. Naturally you expect it to be better than Eclipse or you would’t pay for it. I proceeded to download, install and put IntelliJ to use.

A few words on environment. I run Debian Lenny on a Dell Precision T-3400.

IntelliJ is an easy install. Download, unpack, run (,????, profit!). Its only 100MB compressed which is less than 150MB for Eclipse classic (and a lot less than 650MB for MyEclipse). You may need to check JDK_HOME variables but I’m guessing most people wil have this set up already. Otherwise what are you doing with a Java specific IDE. You may be confronted with a dialog or two. To begin with you should be safe with the defaults. Odds are you only need a subset of the defaults to begin with anyway.

My first impression after the install is that IntelliJ is very pretty. Especially after I changed the theme. This all went really well. Everything was fast and seemed well thought out. Of course IntelliJ has its own key mapping, menu ordering and things of that nature. If you like you can enable Eclipse key mappings but if you want to get to know a program rather than get to work quickly I recommend going with what’s totally unfamiliar. Although I am of the opinion that ctrl-s means save in any language.

The Subversion plugin works like a charm. I am even convinced it’s faster than Subversive…at least in our local environment where Subversion has, at times, been a pain to work with. If for no other reason, this plugin makes me want to use IntelliJ. If my work confined itself to talking to the repository I would be done. Forever.

So here we have a fresh working copy of our project, complete with Eclipse project files. IntelliJ understands Eclipse project files or at least so it claims. An import or two later and I have an official IntelliJ project. As far as I’m concerned I just need to point this puppy to Tomcat and we’re good to go.

Now IntelliJ has a lot of spiffy UI thingies. You got screens for configuring everything. You’ve got modules and facets. You’ve got raindrops on roses and warm woolen mittens. Confidently I configured the project to deploy to tomcat. Of course it wouldn’t work at once, that would be too much to ask. I was convinced any problems I was sure to encounter would be easy to solve.

My first problem comes in the form of compiler errors. “But wait,” you say, “did you not do a fresh checkout? Are your colleagues so daft that they enter broken code?” That would be yes and not usually. IntelliJ seems less permisive than eclipse in allowing certain constructs. Mind you Eclipse has no compile errors on the same code…so it can’t really be a compiler error since they use the same one. Ok, so its a precompile syntax validation check error or whatever. It’s not really a big deal.

Unfortunately I have no clue what IntelliJ is really doing. Somewhere there exists a tomcat. Somewhere there exists at least one copy of this tomcat. Somewhere you may or may not be deploying your project. Ok, I can actually find where IntelliJ hides its tomcat copy. Why can’t it just use my tomcat? I don’t know. Oh you can, sort of, but then you all of a sudden have to start and stop tomcat yourself. Not that I really care that IntelliJ uses a copy of tomcat, except that this copy still uses the originals directories. Sort of. I think. I’m not really sure.

A word on IntelliJ support. If you happen to write them they answer quickly. Really quickly. Actually the reply is there almost before you press compose mail. I was seriously impressed. Unfortunately they couldn’t help me and I dind’t want to rely heavily on support which is mostly meant for paying customers anyway. I also don’t like using support lines in general. It feels like a flaw in the product. Which it is.

You may be asking why I didn’t simply look up the answers in the documentation. IntelliJ documentation is one of the worst I have ever seen. It’s not worse than factually wrong information but it’s not better than a blank piece of paper. Basically if you have something labeled “Perform action” the documentation wil read “Performs the action Action”. The documentation will never actually explain what is happening or go into the details of anything.

So now I have a project which may or may not be deploying somewhere. After some looking around I do figure out I have lots of classpath problems. Also, my ant builds aren’t being run. Ok, add library here, ant build before deploy…Some progress made but not enough. My project still won’t work.

To make a long story short for about a week I’ve been playing with IntelliJ. I’ve installed, reinstalled, checked out, imported, etc, etc. I can’t get our project to work. This is a project which does work under Eclipse. So I blame IntelliJ. Where Eclipse always seems to have the thing you are looking for where you are looking for it, IntelliJ will make you search for it. Where Eclipse forces you to know what you’re doing and setup this and do that, IntelliJ has done it for you (mostly) and otherwise you can pretty much forget it.

To me IntelliJ is like a beautiful woman with a really anoying personality and a deaf ear. I really wanted to like it. Ask my colleagues, I am ready and willing to say that I hate something. I do it regularly and with passion. I do it to Eclipse all the time. Yet, despite all this, I really can’t hate IntelliJ. I would still really like to work with it. I’m convinced it could be really good. I can’t hate it and yet I can’t love it. For now it wil remain the IDE I wanted to love.

Ubuntu and Eclipse: The error was ‘BadAlloc (insufficient resources for operation)’.

19 January 2008

Linux and Eclipse have proved themselves as a killer combination for Java (EE) development. Specially for technology savvy users, which i guess a lot of programmers are, the combination is a dream come true.

Though once in a while things can heat up under the hood.

With the uprise of Ubuntu, meant as a very user friendly version of Debian, many developers are trusting in their Ubuntu/Java/Eclipse environment and with good reason. It installs very easily, runs very fast and provides features like update-notifications, very fast turn around times for security updates and an almost insane amount of hard and software support.

Though the common Linux distributions (may i even say OpenSource) practice of fast turn around on security updates is a very good thing to have. It can once in a while turn into an unpleasant experience. Like today 18 Januari 2008.

To fix a programming error in the Xorg graphical software component of Linux the Ubuntu people pushed out an update for it called xserver-xorg-core_1.3.0.0.dfsg-12ubuntu8.1. I applied this update in the early morning when working at home and when i had to leave to continue working at the office i shutdown my laptop and went to the office as usual.

Only to find out that my laptop was not working as expected when booting up. The login manager appeared (GDM) and i logged in, finding my desktop (Gnome) in a half broken state. Firing up Eclipse was even worse, throwing me the following ‘unclear’ error message on the console:

The program ‘Eclipse’ received an X Window System error.
This probably reflects a bug in the program.
The error was ‘BadAlloc (insufficient resources for operation)’.
(Details: serial 1086 error_code 11 request_code 147 minor_code 5)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the –sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)

Error Message

Now the obvious solution is to reinstall the package version before the security update or wait for the next update.

You can download the old version of the package from the following location:

Install this package with the following command

$ dpkg -i xserver-xorg-core_1.3.0.0.dfsg-12ubuntu8_i386.deb

Now restart your X server by loggin out of your desktop and back in again or restarting your server and you should be fine again.

At the time of writing, which is about half a day after the update hit the Ubuntu servers and i first found myself dealing with this problem, the Ubuntu people are pushing out there second update for the broken xserver-xorg-core package called: xserver-xorg-core_1.3.0.0.dfsg-12ubuntu8.2

You can safely install this new version and have everything working as expected.


Old good version:


Broken updated version:


New good version:


If you want to be safe, wait until tomorrow (19/20 Januari 2008) before you hit the update button, make sure that you updated your apt repository and verify that it’s installing the 8.2 update version of xserver-xorg-core. Then you should be all set to keep your desktop up to date and running like a charm 🙂

Last but not least, the official advisory for this bug:

Debian Security Advisory DSA-1466-2
Package : xorg-server, libxfont, xfree86
CVE Id(s) : CVE-2007-5760 CVE-2007-5958 CVE-2007-6427 CVE-2007-6428 CVE-2007-6429 CVE-2008-0006

The fix for CVE-2007-6429 introduced a regression in the MIT-SHM
extension, which prevented the start of a few applications. This update
fixes this problem and also references the patch for CVE-2008-0006,
which was included in the previous update, but not mentioned in the
advisory text.

Post-Scriptum: currently Ubuntu has released even a third patch to xserver-xorg xserver-xorg-core_1.3.0.0.dfsg-12ubuntu8.3
