Hello

After a debugger crash in my eclipse 2.1 environment I installed
Eclipse 2.1.1 in a new empty directory and reimported the plugin which
I'm developing.

After running "Run-time Workbench" I always get the following stack trace.
Does someone knew what's going wrong?

Is you plugin registering launch groups? Or a launch history action?
I would set an exception breakpoint for NullPointerException, debug a
runtime workspace and see the root of the problem.
