When you use the IDE for one or more hours you can get an strange behaviour: you can have an error on a Java file but the IDE doesn't mark with red the error. 

The workaround is restart the IDE, but it's very cumbersome

Could you please create a thread dump next time you reproduce the problem? Thanks.
Comment 2 Tomas Zezula 2014-08-06 12:25:07 UTC 
Waiting for thread dump or self sampler file.
Comment 3 Tomas Zezula 2014-08-06 12:26:59 UTC 
Here is help how to generate thread dump: http://wiki.netbeans.org/GenerateThreadDump

Thank you for your attention and guidelines. The last times I had this bug I forgot to take the thread dump. The next time I catch this bug, you can make sure I gonna send you the thread dump

Comment 11 Dusan Balek 2014-08-18 11:12:07 UTC 
As can be seen from the error stripe on the right side of the editor, there is an error displayed near the beginning of the source file (see the attached screenshot from comment 9). What is the message of that error?
Comment 12 iluvtr 2014-08-18 13:34:38 UTC 
I don't remember that message
Comment 13 iluvtr 2014-08-18 16:56:08 UTC 
I think this problem comes when NetBeans starts alerting 'Low memory to compile classes', and the memory is almost full. Maybe you could reproduce this bug assigning your test IDE a lower -Xmx, and trying to make some changes to Java classes in order to fill the memory.
Comment 14 Dusan Balek 2014-08-19 09:11:18 UTC 
Could you please attach a memory heap dump?
