Description Exceptions Reporter 2013-09-06 10:07:59 UTC 
This bug was originally marked as duplicate of bug 226654, that is already resolved. This bug is still valid, so this seems to be another bug, but it might be related.

23s of http://statistics.netbeans.org/exceptions/exception.do?id=701530 is spent in 

org.netbeans.modules.form.GandalfPersistenceManager.loadForm()	77.7332	13 602 ms (77,7%)	13 572 ms	1

some of them could be offloaded from EDT - like scanning classpath (3s?), but otherwise it is slow classloading problem (because of overloaded I/O?).
Comment 3 Tomas Pavek 2013-12-18 17:15:59 UTC 
The snapshot 701530 from form loading is wrong here. It's completely unrelated to the first report (690212). It has nothing to do with InstalledFileLocatorImpl either. It belongs to bug 179407. This bug has enough reports already and this one is not particularly interesting so I will not move the report there - mainly not to make some future slowness reports with InstalledFileLocatorImpl be duplicated there.

The original report (690212) seems to be something from autoupdate.

This should be fixed by http://hg.netbeans.org/core-main/rev/595295d8cfb9
