I'm sorry, but if you have a Java 6 installation on your machine as a result of upgrading from Tiger with a Developer Preview installed, it does not work on Leopard due to to binary incompatibility.

We have been able to replicate this failure, and unfortunately it affects Java Preferences and Web Start. If you also had Java 6 specified as your preferred Java Application Runtime in Java Preferences, this now also breaks /usr/bin/java and the related tools on the command line.

If you remove or move aside the

/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0

directory, as well as the "1.6" symlink in "Versions", that should restore your Java installation on Leopard to a working state.

We normally do not advise tinkering with the internals of the JavaVM.framework, however in this instance, it does appear to be necessary.

Our sincerest apologies for this oversight,

Mike Swingler

So it does work then? Or at least it SHOULD work. I'm very confused. If anyone can confirm running 1.6 on Leopard that would be great.
