Description ChemMitch 2015-08-11 17:16:38 UTC

Steps:
1) Start NetBeans
2) Open projects
3) Right click on 1 project> Properties
4) Navigate to Libraries
5) Select one Library
6) Click Edit
7) Leave NetBeans for a few minutes.

Now NetBeans is locked up and I must use Task Manager to close.

Observed this issue on a Windows 2012 VM

Mitch, could you please generate a full thread dump [1] taken when the NetBeans is locked and attach it to this issue? Then please reopen this issue. Thanks!

I ran NetBeans from a console window as specified in the link.  
NetBeans locked up again when I edited a library (Note: several edits went OK but just now it locked up again).
No thread dump appears in the console window, though.

Comment 4 Jiri Kovalsky 2015-09-22 10:08:59 UTC

The full thread dump does not show up automatically when the IDE deadlocks. Did you press Ctrl-\ in the terminal console you used to start NetBeans?

Comment 5 ChemMitch 2015-09-22 16:50:53 UTC

Yes; Windows responds 
''∟' is not recognized as an internal or external command,
operable program or batch file.'

no thread dump.

You are supposed to press Press Ctrl-Break in Windows, not Ctrl-\. :)
