Apple has released Java 2 Standard Edition (J2SE) 5.0 Release 4 delivers numerous enhancements for the Apple implementation of J2SE 5.0 on Mac OS X v10.4.
J2SE 5.0 Release 4 improves reliability and addresses issues found in earlier releases of J2SE 5.0 for Mac OS X. After installing J2SE 5.0 Release 4, J2SE 5.0 becomes preferred over Java 1.4.2, which will still be installed on your Mac. Applications run with J2SE 5.0 unless they specifically request Java 1.4.2.
This release provides compatibility with Sun’s Java 2 Platform Standard Edition, version 5.0 (1.5.0_06).
J2SE 5.0 Release 4 is available via Software Update.

I’ll post the rollback anyway and you can choose to do it if you want. Here goes:
openterminal on your mac
tocheck your java version, type:java –version
ifyou’re on version 1.5, type:cd /System/Library/Frameworks/JavaVM.framework/Versions
type:ls,you’ll get all your versions there (1.3.1 , 1.4.2, …. 1.5)
remove the current JDK link by typing:sudo rm CurrentJDK (it will ask your root or /admin password, but nothingis visible when you type it)
type:ls to make sure the CurrentJDK file has been removed
recreatethe link to your former java version by typing:sudo ln –s 1.4.2 CurrentJDK
makesure you’re now on the right version: java –version (it should now say 1.4.2)
THIS IS IMPORTANT
all this is case sensitive and take note of all spaces otherwise you will not get the right result, colons denote the prompt in the Terminal so you don’t need to type them. UNIX is a pain if you haven’t used it before as 1 incorrect keystroke and it wont work, you will get an error, if you do you can keep trying but it’s important not to ‘stray from the path’ if you are not familiar with it as you could damage the system and it won’t give you any warnings. I can’t be held responsible for anyone not following these instructions correctly. So be warned.
Hope this is some help
just to clarify
line 4 on the instructions you do not need to type the comma after ls
Thanks Andy, I had a similar problem with the new version of Java for OSX. I wish the support for Java was better and a lot better for j2me! ( I want a wireless tool kit from Apple or Sun, doesn’t matter who…), but i guess i just have to keep hacking out these problems, hehe,
