We have an app that has been running fine with RCP over WebStart for
more then a year now on Java 1.5

Launching it on the new Java 6 results in a crash with th following
error message dumped in the log:

Any ideas on how to get this to work on Java 6? We're still on RCP 3.1.

I think that only Eclipse 3.2+ work with Java 6.

Tried upgrading the RCP framework to 3.2.1, but that only made things
wose. Now I'm not even getting an error message! The client just dies on
launch...

Anybody from Eclipse that has a solution to this?

Have you rebuild your RCP deployment after Eclipse and compiler version
update? You should also ensure a clean start, most safely done by
deleting the runtime workspace (if possible) and all contents of the
"configuration" directory despite the config.ini file).
I use the Java 1.6 compiler since two weeks w/o any problems in my
RCP app, having done several deployments during this time.

This will be addressed for 3.2.2. A patch is pending in one of the bug
report of equinox framework or runtime.
Sorry for not providing the details, I don't have access to everything where
I'm from.
