Just saying THANKS – you’re tip showed that I had a FUBAR Versions directory, and by changing the CurrentJDK link, I’m back in business. Shame about my MagicDraw though. Hopefully someone will figure a workaround.

Apple are trying to sabotage Java ?!

I ahd to convert back to Java1.5 as default. To do this I changed the /System/Library/Frameworks/JavaVM.framework/Versions to look just as described in the original posting. I had Current pointing to 1.5.0 then 1.5, but it needs to point to A, and CurrentJDK to 1.5. So an ls -l gives:
lrwxr-xr-x 1 root wheel 5 Oct 9 2008 1.3 -> 1.3.1
drwxr-xr-x 3 root wheel 102 Jan 14 2008 1.3.1
lrwxr-xr-x 1 root wheel 5 Oct 9 2008 1.4 -> 1.4.2
lrwxr-xr-x 1 root wheel 3 Jun 15 2008 1.4.1 -> 1.4
drwxr-xr-x 8 root wheel 272 Jun 14 2008 1.4.2
lrwxr-xr-x 1 root wheel 5 Oct 9 2008 1.5 -> 1.5.0
drwxr-xr-x 8 root wheel 272 Jun 14 2008 1.5.0
lrwxr-xr-x 1 root wheel 5 Oct 9 2008 1.6 -> 1.6.0
drwxr-xr-x 8 root wheel 272 Jun 15 2008 1.6.0
drwxr-xr-x 8 root wheel 272 Oct 9 2008 A
lrwxr-xr-x 1 root wheel 1 May 17 23:22 Current -> A
lrwxr-xr-x 1 root wheel 3 May 17 23:23 CurrentJDK -> 1.5

This is what i have

lrwxr-xr-x 1 root wheel 5 Jan 15 12:24 1.3 -> 1.3.1
drwxr-xr-x 3 root wheel 102 Sep 29 2007 1.3.1
lrwxr-xr-x 1 root wheel 5 Jan 15 12:24 1.4 -> 1.4.2
lrwxr-xr-x 1 root wheel 3 May 17 2008 1.4.1 -> 1.4
drwxr-xr-x 8 root wheel 272 Mar 7 2008 1.4.2
lrwxr-xr-x 1 root wheel 5 Jan 15 12:24 1.5 -> 1.5.0
drwxr-xr-x 9 root wheel 306 Feb 2 16:33 1.5.0
lrwxr-xr-x 1 root wheel 5 Jan 15 12:24 1.6 -> 1.6.0
drwxr-xr-x 9 root wheel 306 Feb 4 11:57 1.6.0
drwxr-xr-x 9 root wheel 306 Feb 2 16:34 A
lrwxr-xr-x 1 root wheel 3 Feb 4 12:01 Current -> 1.5
lrwxr-xr-x 1 root wheel 5 May 10 14:03 CurrentJDK -> 1.5.0

and I have also uncommented the -vm option in info.plist to point to /System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Commands/java

Now when i double click on eclipse.app, i see the -vm as /System/Library/Frameworks/JavaVM.framework only and it terminates with JVM Terminated -1.
I am pasting the full trace here….any help

for instance, if you turn on -debug, or read the ‘JVM terminated’ dialog, the ‘-vm’ option always says

-vm /System/Library/Frameworks/JavaVM.framework

regardless of whether you use -vm from the command line, Info.plist *or* eclipse.ini . that’s a pretty serious red herring which kept me fighting this for hours. especially when other blogs claim that there’s no solution due to Carbon vs. 64 bit issues:

the solution above works great. thanks
