Unfortunately this indicates that views update in insertUpdate/removeUpdate did not update last view's end offset properly and so

  Rectangle rec2 = component.modelToView(view.getEndOffset() - 1);

picks a wrong offset.
Is this a reproducible problem or random?

Comment 3 aldobrucale 2011-02-23 15:59:17 UTC

It happens randomly, but it does happen once in a while. I was undoing a long list of changes, keeping ctrl-z pressed: may be a threading problem? Is there any runtime flag I may set to facilitate debugging if it happens again?

Comment 4 Miloslav Metelka 2011-03-10 14:14:05 UTC

Yes, it was a race condition. I believe that the changes in issue 195432 should eliminate this problem as well so I mark it as duplicate.
If the problem would persist even in 7.0 RC1 please reopen the issue. Thanks.
