Would have submitted using exception reporter, but that threw an exception too. :-(

(and then three more times).

Prevented me from deleting an unused import: accepting the hint, or simply selecting the line and hitting BACKSPACE, caused the line to be deleted momentarily but then immediately reappear. Marking P2 since it broke even "dumb" text editing.
Comment 1 Jesse Glick 2009-12-01 13:13:25 UTC 
Does not seem to occur in

NetBeans IDE Dev (Build 091130-47261225e968) (#47261225e968)

so may be a regression (unless it was only happening in one IDE session for unrelated reasons).
Comment 2 Max Sauer 2009-12-01 15:01:59 UTC 
Already fixed, thank you for your report anyway.
