Reassigning to java/Source. Please evaluate.
Comment 3 Svata Dedic 2015-07-31 09:22:14 UTC 
great, reproducble using data from ER 782653
Comment 4 Svata Dedic 2015-07-31 13:24:17 UTC 
The issue was caused by incorrectly assigned comments. A comment from some deep of + binary tree operator was assigned to the outermost op, so when the code changed to append(x), the 'x' attempted to copy wrong offsets.

Fixed in jet-main#c35d8f62b9d3
Comment 5 Quality Engineering 2015-08-05 01:19:07 UTC 
Integrated into 'main-silver', will be available in build *201508050002* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
