duetoNullPointerException
This seems to correspond to bug # 239736 and I've added a comment to
that report to include the 1.4 version as well.
I would also be interested in helping to patch it if needed, but would
need a starting point as well.

We too have the same problem.
To be precise, the error stack trace is enclosed below.
Please note that the same behaviour occours for each out of the three VE
installations proposed at the VE wiki
(http://wiki.eclipse.org/VE/Installing)

Hello,
I'm using Eclipse 3.4 with VE, but opening ViewParts and EditorParts
doesn't work. I spent a lot of hours trying to fix the problem, but
debugging a multi VM application with multiple threads is not easy :-(.
Does anyone have a clue, what might cause the occuring
NullPointerException, or on which part I should concentrate to find the
bug? It must be an incompatibility issue with Eclipse 3.4, I think. Does
anyone know, which change in Eclipse 3.4 might cause this effect?
I really would like to fix this bug and contribute the patch.
Cheers,
