IDE hung on project reopen (close project from one repository, open same project from another repository).
Hang was once after repeating operations some times.
Created attachment 71110 [details]
seems that the AWT thread is waiting for "Versioning long tasks".
Is it reproducible? Could you just "wait" a little bit more? Maybe the VCS operation takes a time?
anyway, reassigning to ant/freeform for evaluation
I waited about 10 minutes and kill IDE.
Thread dump was not changed.
Note: normal reopen on my computer takes about 5 second.
Fixed. Project metadata are read under PM.mutex.readAccess now.
Actually setting to fixed.
Integrated into 'main-golden', will be available in build *200810070201* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
