Max Andersen commented on JBIDE-651:
------------------------------------

Sure I can see where in code a NPE is caused but how to reproduce it ?

Note this is the VM failing just because a NPE occurs, not much we can do about that since NPE's will occur since we can't guarantee against NPE's ;)

The vpe on linux is seperate issue.
