Currently working IDEs

[Erik Mattheis]

I'm running OS X 10.6.6 on a MacBook Pro with Core 2 Duo. I installed OpenJDK with the installer from the openjdk-osx-build project <http://code.google.com/p/openjdk-osx-build/>. Next I downloaded Eclipse Classic 3.7.0 M4 for 64 bit Cocoa, expanded the archive and performed the following on the command line:


$ export JAVA_HOME=`/usr/libexec/java_home -version 1.7`
$ echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home
$ java -version
openjdk version "1.7.0-internal"
OpenJDK Runtime Environment (build 1.7.0-internal-b00)
OpenJDK 64-Bit Server VM (build 20.0-b03, mixed mode)
$ cd Downloads/eclipse
$ java -XstartOnFirstThread -jar plugins/org.eclipse.equinox.launcher_1.2.0.v20101119.jar -os macosx -ws cocoa -arch x86_64
***WARNING: Display must be created on main thread due to Cocoa restrictions.
An error has occurred. See the log file


The log file contains the following:

If you simply edit the eclipse.ini and add a -vm argument pointing to the java executable, Eclipse launches, but if you got to 'About Eclipse' in the application menu, click 'Installation Details' and select the 'Configuration' tab, you'll see that Eclipse is actually running on the Apple 1.6 JDK. Attempting to manually launch Eclipse using the OpenJDK java executable like this:
