Comment 3 _ gtzabari 2014-02-16 06:21:48 UTC 
After reporting this bug, the IDE became non-responsive forcing me to terminate Netbeans (some task was running endlessly on the EDT). I don't know whether it is related to this issue or not, but I thought it's worth mentioning.

Thread dump

It happened again, so I'm attaching a thread dump for your review.
Comment 5 _ gtzabari 2014-02-16 06:30:00 UTC 
Increasing priority (because this takes down the entire IDE, every time), and attaching a parser dump file for your review.

Parser dump file
Comment 7 _ gtzabari 2014-02-16 06:45:26 UTC 
This parsing error is caused by the fact that the code invokes "continue" from within a lambda expression instead of "return". This should be flagged as a compiler error, but instead it triggers this parsing bug.
Comment 9 _ gtzabari 2014-02-17 15:20:46 UTC 
Dusan,

Before closing this bug, I suggest fixing the secondary bug which is: why does Netbeans crash when javac throws AssertionError? (Or should I file a separate bug for that?)
Comment 10 Dusan Balek 2014-02-17 16:10:52 UTC 
Unfortunately, I was not able to reproduce the NB crash (only the AssertionError itself). So, if you have a reproducible test case for the crash, please, file a separate bug for it. Thanks.
