Description Petr Jiricka 2010-04-23 14:55:12 UTC 
1. The IDE was in the middle of long scanning. I pressed the "Profile Me" buttom in the toolbar - the icon changed. 
2. After a while I pressed it again to finish the self-profiling. The button became gray, but the snapshot did not appear in the editor area.

Though now I see that there is a heapdump.hprof file in my userdir (555 MB). I can provide it if requested.
Comment 1 Petr Jiricka 2010-04-23 21:10:41 UTC 
The above happened while scanning the entire GlassFish sources.
Regarding the heapdump, when I looked at the objects by retained size, there were the following interesting classes:

org.netbeans.core.ui.sampler.SamplesOutputStream - 47 MB
org.codehaus.plexus.DefaultPlexusContainer - 42 MB
many java.lang.ref.Finalizer -  >5 MB each

Profile me feature is a part of profiler module - reassigning
Comment 3 Tomas Hurka 2010-04-26 10:59:52 UTC 
Should be fixed in latest dev. build.
Comment 4 Petr Jiricka 2010-04-26 22:15:28 UTC 
Which build fixes this? I am still getting the following in the latest build:

WARNING [org.netbeans.core.TimableEventQueue]: too much time in AWT thread org.netbeans.core.ui.sampler.SelfSamplerAction$Controller@f42879c
WARNING [org.netbeans.core.TimableEventQueue]: no snapshot taken
Comment 5 Petr Jiricka 2010-04-27 07:47:45 UTC 
Sorry, my mistake, then it appeared after a while.
Comment 6 Tomas Hurka 2010-04-27 07:59:29 UTC 
Ok, FYI:  Yesterday I added progress to saving snapshot. See issue #184947.
