I was importing some binary plug-ins. I had a class file editor open along with 
several compilation unit editors. The progress dialog disappeared, but the 
wizard remained. When I looked in my log I found this:

!MESSAGE Unhandled exception caught in event loop.

Comment 1 Jerome Lanneluc

Code at line 1036 of SourceMapper.java cannot throw a NPE:

public void mapSource(IType type, char[] contents) {
  this.mapSource(type, contents, null); // line 1036
}

Is it another case of jit problem with SR2?

Comment 2 Darin Wright

Could be, not sure that I can reproduce the problem.

Comment 3 Philipe Mulet

Darin, do you confirm you were running JRE SR2 at the time it occurred ?

Comment 4 Darin Wright

2003-03-17 15:05:07 EST

Yes, I was running SR2.
