Threaddump

I added a text in one of the open files causing a number of compiler errors to be flagged in the file. The IDE became fully unresponsive almost immediately.
In console the process shows irregular CPU usages at 2.5% with an steady increase in heap use with a period of just over 2 minutes.
Attached a thread dump of the process.

I do not see a real dedlock though passing to filesystems for evaluation. Perhaps the Android lint is just taking long: org.netbeans.modules.android.lint. Reporter is this a real deadlock or just the editor problem?

This wasn't just slowness. I have had that happen too, up to 3 minutes such slowness could be. After this one lasted for about 10 minutes in which I observed the CPU and GC use, i decided to kill NB and continue with my coding.
I have a second stack dump about 4 minutes later/earlier than the one included in the bug report. (file times 19:44 and 19:48, I can't see which one I have included)

Thank you for the heap dump, but we will need Profiler Snapshot or Heap Dump to investigate this problem.
See http://wiki.netbeans.org/FaqMemoryDump and http://wiki.netbeans.org/FaqProfileMeNow.

The problem is very similar to bug 250349, maybe it is a duplicate.

Closing as incomplete for now. Please reopen if you can reproduce the problem and attach additional data.
Thank you very much.
