I am having a similar problem.

After working with JDK1.2 beta 3 for  a couple of months with generally good results, I
downloaded beta 4 a couple of weeks ago and had problems immediately because of changes in the
JDK related to the "classes.zip" file.  In beta 4, there is none.   Instead beta 4 uses a
"rt.jar" file found in the "jre/lib" directory.  I found no mention of this major change and
got no help from SUN when I emailed and called them.  I was pretty miffed, after three
downloads (all successful) and trying for two days to figure out where I was going wrong, only
to find out that they had failed to warn people.

Anyway, I finally found out about the "rt.jar" file and configured JBuilder to use it.  When I
do, JBuilder complains that it can't find some kind of JIT called "javacomp".  It continues to
eventually run the app. despite this hiccup.  The problems arise when the code starts to run.

For some unfathomable reason, the thing doesn't repaint correctly with the effect that popup
menus have a ghostly transparent appearence and when the menu drops, other objects that had
appeared fine before the popup appeared suddenly disappear only to be repainted if I click on
the spot where they once were visible.

All very strange and annoying enough that I don't want to take the time at this point to try
and figure it out.  I've returned to beta 3 for now.
