One of the users here, who, unknown to me, had administrator rights on
his MacMini, ran the software update as prompted by Software Update.
The update contained a Java update, and since installing he has not been
able to run a required Java application. The supplier of the Java app
have been informed of this and I'm hoping the can find a fix - but I
don't know how long they'll take. In the mean time is there any way we
can roll-back this change, or persuade a previous version of Java to
handle this app?

Thank you for any help you can give with this problem.

Justin.

The "Java Preferences" app lets you set which java you want to use by
default. I *think* this also sets symlinks from /usr/bin/java to
/System/Library/Frameworks/JavaVM.framework/Versions/<somewhere> so you
could try looking under there for old versions of the JVM and try
fixing up things to use them. (Play with Java Preferences first as
that's probably more supported :-)

On my box here though, no old versions of the JVM are present, so I
think you might be screwed. There's no straightforward way to rollback
an OS update.
