Description Tomas Mysik 2013-07-04 13:35:40 UTC 
Discovered while investigating issue #225419 that these snapshots belongs to this area. The snapshots can be found in Exception Report URL, please evaluate them, thanks.

snapshot-654706:
org.netbeans.modules.java.j2seproject.J2SEProject.createLookup()	45.96735	1 683 ms (46%)	1 664 ms

snapshot-676848:
org.netbeans.api.project.ProjectManager.findProject()	68.050476	16 535 ms (68,1%)	16 376 ms
FoD calls it and J2SE and Glassfish do something, not sure if it is OK or not.

snapshot-660975:
org.netbeans.spi.java.project.support.ui.SharableLibrariesUtils.execute()	99.98184	10 667 ms (100%)	709 ms
It calls org.netbeans.core.windows.services.DialogDisplayerImpl.notify() under write mutex.
Comment 1 Tomas Zezula 2013-07-09 12:34:04 UTC 
snapshot-654706 in fact invalid from java project point of view:
OpenProjectList holds the writeLock.

snapshot-676848 invalid as well, the WM is required by J2SELTP writing the libs classpath.


snapshot-660975 fixed jet-main f562e2271096.

Anyway from my point of view the problem is not in holding the WL but reading the data under RL from EDT.
