Today would have marked Maurice’s 30th birthday, if it weren’t for that unfortunate accident almost a year ago. It is times like these when you remember the loss of a valued friend more so than normally. No more sharing of cake, taunting the additional year and celebrating life.
My iCal notified me yesterday of Maurice’s upcoming birthday, and today again. It will keep on doing that next year, and the year after that…
Maurice you are sorely missed. My thoughts are with you and Michel and your family. Where ever you are, happy birthday!

With the invaluable help of David Green, I was able to run Eclipse on openjdk 6 on my first gen MacBook Pro (you know, those left behind by Apple, running on a 32 bit CoreDuo processor… good to know that Apple supports the early adapters).
With this script that I adapted from David’s blog I was able to start Eclipse 3.4 (Version: 3.4.2
Build id: M20090211-1700) with Landon Fullers openjdk 6 build:
export JAVA_HOME=/Developer/Java/openjdk6-b16-24_apr_2009-r1
export PATH=$JAVA_HOME/bin:$PATH
java -server -Djava.library.path=$HOME/bin/jnilib -Dswt.library.path=$HOME/bin/jnilib -Xms128m -Xmx768m \
-XX:MaxPermSize=192m -Dosgi.requiredJavaVersion=1.5 -Dorg.eclipse.swt.internal.carbon.smallFonts \
-cp /Applications/eclipse/Eclipse.app/Contents/MacOS/../../../plugins/org.eclipse.equinox.launcher_1.0.101.R34x_v20081125.jar \
org.eclipse.equinox.launcher.Main -os macosx -ws carbon -arch x86 -showsplash \
-launcher /Applications/eclipse/Eclipse.app/Contents/MacOS/eclipse -name Eclipse \
--launcher.library /Applications/eclipse/Eclipse.app/Contents/MacOS/../../../plugins/org.eclipse.equinox.launcher.carbon.macosx_1.0.101.R34x_v20080731 \
-startup /Applications/eclipse/Eclipse.app/Contents/MacOS/../../../plugins/org.eclipse.equinox.launcher_1.0.101.R34x_v20081125.jar \
-launcher /Applications/eclipse/Eclipse.app/Contents/MacOS/eclipse \
-keyring $HOME.eclipse_keyring -consoleLog -showlocation -vm $JAVA_HOME
The script misses the shebang, since my hosting provider thinks that I’m trying to execute some serverside exploit…
You’ll have to extract a couple of shared libraries that are packaged in your Eclipse distribution:
jar xfv /Applications/eclipse/plugins/org.eclipse.swt.carbon.macosx_3.4.1.v3452b.jar
jar xfv /Applications/eclipse/plugins/org.eclipse.core.filesystem.macosx_*.jar os/macosx/liblocalfile_1_0_0.jnilib
You’ll have to rename all those libraries to give them a *.dylib extension.
Finally I had to point /System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home to the openjdk 6 directory:
sudo mv /System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home /System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home.old
sudo ln -s LOCATION_OF_OPENJDK /System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home

There is quite some anti-mavenism going around, about plugins suddenly not working, etc. And often this is true, case in point: maven-eclipse-plugin version 2.6 botched all projects working with Wicket by being very anal about what should live in the src/main/java directory tree (only Java files! God forbid you’d like to put web resources such as .properties (i18n for your web components), .js, .css, .html, etc next to your Java files. This version not only broke Wicket projects, but AspectJ as well.
Fortunately, the Maven community (more specifically Barrie Treloar and Arnaud Heritier) were helpful in finding the root cause of our pain: a conflict in merging the resources paths during the classpath generation.
With the latest snapshot of maven-eclipse-plugin 2.7 we now have our old build stability back, and can enjoy the new features of the maven-eclipse-plugin, such as searching your workspace for projects that are snapshot dependencies, and adding a project link instead of a jar dependency.
Yes, maven can sometimes be a pain, but ultimately with a great supporting and responsive community it will deliver. Many thanks to Barrie and Arnaud for being patient with us.

From Slashdot:
‘This means you can write a 100% reliable exploit in pure Java. This exploit will work on all the platforms, all the architectures and all the browsers,’ —
And the Java critics said total platform independence was impossible!
(yes I know that this is only affecting OS X Java, the quote was just too good to waste).

I have my share of complaints like everybody else about Apache Maven and one of them is that upon installation (or upgrading to a new plugin version) it starts downloading half of the available internet. Maven is constructed in a highly modular fashion, requiring lots of different, small, focused Java libraries. I’d like the distribution to contain those libraries, but I digress. Tonight I saw that not only Maven is structured this way. It is something *all* open source projects got.
For example, the much touted Ruby on Rails project with their disdain for everything Java would probably cringe at Maven (it uses XML after all). But installing Ruby on Rails and for example Radiant CMS with some plugins is a futile attempt in finding the right invocations of: script/*, rake, gem, port and other commandline tools you’ll want to get familiar with. All these tools start downloading stuff from the internet from different repositories (SVN, ruby forge, etc).
Maven: you’re not alone anymore in downloading the internet for your builds…
