Fixed in jet-main.

http://hg.netbeans.org/jet-main/rev/b8fb2434cbf4

If you have reproducible steps to find why caret is null, I would like to investigate it more. I couldn't reproduce this issue.
Comment 3 _ gtzabari 2015-07-01 15:46:09 UTC 
Perhaps it makes sense to add an assert() in front of "return false" to help you get future reports of how to reproduce this...
Comment 4 Quality Engineering 2015-07-03 01:19:40 UTC 
Integrated into 'main-silver', will be available in build *201507030001* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
