This was running on eclipse 3.1 final.

Selected some text, did a ctrl-X and got the first exception below. Undo worked
after the cut. A subsequent paste did paste the text, but also triggered anNEP
(second exception below).

After closing and reopening the file the exceptions were no long thrown.

I originally posted this an eclipse bug 102547. You might be interested in this part of their response:

FYI … I can see the BasicStructuredDocument is from our SSE code in WTP, but
… the “com.ibm.sse.model.internal.text” package indicates its something pretty
old. (that is, not sure its valid to be running it with Eclipse 3.1).

Does this NPE happen on every cut, or just a particular one. Can you provide us with a small example file that shows the issue so we can address it?
