OpenJDK 7 on OS/X and IntelliJ IDEA EAP

During the last weeks, Apple started to contribute it’s Aqua/Cocoa port to OpenJDK 7 on the macosx-port branch. It’s still works it progress but it was nice to see some SWING apps like IntelliJ IDEA works on the preliminary release.

I used IntelliJ IDEA EAP (10.5) and tweaked it’s startup shell.sh to define AWT_TOOLKIT=CToolkit and add -Dswing.defaultlaf=com.apple.laf.AquaLookAndFeel since Aqua Look and Feel is not default for now.

export CLASSPATH

LD_LIBRARY_PATH=.:$LD_LIBRARY_PATH
export LD_LIBRARY_PATHAWT_TOOLKIT

# AWT/Cocoa port for OpenJDK 7 macosx-port
export=CToolkit
JVM_ARGS="-Dswing.defaultlaf=com.apple.laf.AquaLookAndFeel $JVM_ARGS"

cd "$IDEA_BIN_HOME"
while true ; do
  $IDEA_JDK/bin/java $JVM_ARGS -Djb.restart.code=88 $IDEA_MAIN_CLASS_NAME $*
  test $? -ne 88 && break
done

Then defined OpenJDK 7 from macosx port (available here) as default JVM and started IntelliJ by calling its shell script :

export JAVA_HOME=/Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home
/Applications/IdeaX-IU-106.396.app/bin/idea.sh

And I could see a Swing based application running on OpenJDK 7 and OS/X.

IntelliJ IDEA is so the second major IDE to be compatible with OpenJDK 7 and OS/X – Cocoa, first one was Eclipse thanks to it’s SWT/Cocoa bridge.
I tested with both NetBeans 7 RC1 and RC2 but it didn’t works. I hope it will be fixed in NetBeans 7 final release.

OpenJDK 1.7 for OS/X benchs

After building and packaging OpenJDK 1.7 for OS/X, I wanted to see how performed new VMs.

Test vms

Recents OpenJDK 1.7 32 and 64bits where used :


openjdk version "1.7.0-internal"
OpenJDK Runtime Environment (build 1.7.0-internal-henri_2010_12_01_00_46-b00)
OpenJDK Server VM (build 20.0-b02, mixed mode)



openjdk version "1.7.0-internal"
OpenJDK Runtime Environment (build 1.7.0-internal-henri_2010_12_01_00_49-b00)
OpenJDK 64-Bit Server VM (build 20.0-b02, mixed mode)


Test system

My test system is an Apple Mac Book Pro (MacBookPro5,1) with Intel Core 2 Duo 2.66Ghz and 4Gb DDR3 1067Mhz, running under SnowLeopard 10.6.5 32bits.

DaCapo Benchmarks

I used again DaCapo 9.12-bach, discarding batik test, this one requiring a working AWT/Swing support .

Bench tests launched with -n X, ie (java -jar dacapo-9.12-bach.jar -n 10 pmd)

Conclusion

Good news, two tests Tomcat and tradebeans now pass the bench

OpenJDK 1.7 64bits perform better than OpenJDK 1.7 32bits and OpenJDK 6.

Even if OpenJDK 1.7 32bits performances are better than Apple Java 6, it’s allways behind OpenJDK 1.7 64bits version on OS/X, so you should select the 64bits version if performance is the key for your use.

Next article will cover OpenJDK 1.7 and jtreg, the Regression Test Harness for the OpenJDK platform.

Gildas and I create a project on GoogleCode where we’ll maintain build/package scripts and provide packages.

My Dropbox download page was overloaded and we needed another location, here is it :
