It looks like checking for LowMemory does not work well.
Comment 5 Tomas Hurka 2012-11-05 10:38:17 UTC
Heap dump available on request.
Comment 6 Tomas Zezula 2012-11-05 15:37:27 UTC
Added logging jet-main 406bbad27b82.
Seems a problem with MemoryMXBean.
Please can you run the IDE with option and retry to reproduce the problem?
You will need a build containing the changeset 406bbad27b82.

 Max memory: 1.908.932.608, Used memory: 1.617.979.552,

Log-File after restarting (OOME occured again)

Yesterday this was the same story:
-) I refreshed some source files (update CVS)
-) NB started Background-Scanning -> OOME occured
-) I restarted NB -> OOME occured again
-) I restarted NB -> OOME occured again
-) I cleared the Cache-Directory and startet NetBeans again -> It works

Tomas, you are looking into this, right?
Comment 14 Tomas Zezula 2012-11-20 22:11:28 UTC
Restored the behaviour of LowMemoryWatch not to cross the CMS stop the world limit.
