How to fix broken Java ?

Im on 10.5 and as part of installing some software I switched my Java version by changing the symbolic link /System/Library/Frameworks/JavaVM.framework/Versions/Current so it pointed to 1.6 instead of 1.5. This broke some other software I need for my day-to-day work so I tried to switch back to 1.5 but it didn't work. Now Java is broken on my machine:

# java -version
Failed to open library /System/Library/Frameworks/JavaVM.framework/JavaVM
Failed to find scheduleUpdateSharing in JavaVM library: invalid handle passed to dlsym()
Bus error

Anyone know how to fix this?

MacBook Pro 17", Mac OS X (10.5.8)

See the steps in http://hints.macworld.com/article.php?story=20100123192950640 and http://wiki.oneswarm.org/index.php/OSX_10.6_SnowLeopard and then reverse them.

Then, reverse the steps you used to do the original switch. I realize you're running Leopard, but those were the only posts I could cite that mentions reverting.

The first thing I tried was reversing those steps and then the next thing I tried was Googling. In other words, I only posted here when I had exhausted the obvious options. I was hoping someone from Apple that was more knowledgeable about the Java runtime on Mac OS X would have some more insight.

I downloaded and (re)installed the last 10.5 Java update by removing the old 1.5 folder and copying this new tree into place and replacing the sym link. Now at least I can run java -version and get the proper response:

$ java -version
java version "1.5.0_19"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_19-b02-304)
Java HotSpot(TM) Client VM (build 1.5.0_19-137, mixed mode, sharing)

(previously I was getting a bus error).

I still can't run any Java applications (like Cyberduck or Eclipse) so Im still dead in the water as far as apps go.

The error I get when I run Eclipse is:

2010-11-14 22:45:30.591 eclipse[35224:10b] Cannot find executable for CFBundle 0x100120f10 </System/Library/Frameworks/JavaVM.framework> (not loaded)

Just in case, I downloaded the latest Java update for 10.5 and installed it.

Eclipse runs and Java Preferences actually runs now! <big sigh of relief>
