Comment 2 Svata Dedic 2012-09-14 08:44:00 UTC 
Got it. My thinking about boudary conditions in that case was bad - the error happens in situation, where mouse is clicked at the end-of-fold mark, but BELOW the end mark, which should have no effect (in your case, I assume no outer fold exists). In other cases (e.g. fold ending and another starting on the same line), it should collapse the next fold (also raises an error). 

I'll relax the sanity check.

Message:   Issue #218257 - IllegalStateException: non-parent fold without fold mark: fixed
2nd half of folder indicator can belong to no fold or an arbitrary one, if more folds start/end at the same line. Relaxing checks.

Integrated into 'main-golden', will be available in build *201209150001* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
