can't reproduce in

Product Version: NetBeans IDE Dev (Build 201111140600)

System: Windows 7 version 6.1 running on x86; Cp1252; en_US (nb)

It's reproducible. I've tried this on Linux Ubuntu 11.10 and on Windows 7. And I increase the priority to P2, because it's too visible and maybe too often bug.

in some cases there are two 'toolbars' sub-menu instance even after startup with a clean user dir.

jardo, could this be related to some of your changes in menu/actions?

to reproduce:
- start IDE
- press ALT+V to show 'View' submenu immediately after the main window is shown

this is probably a side-effect of fix #201494. the task which creates menu item is still running while the org.openide.awt.MenuBar$LazyMenu.setPopupMenuVisible(true) is called. that fires another task which creates the second instance of toolbars submenu.
see attached log file.

(reverting the fix for #201494 fixes this problem)

maybe we can also downgrade this to P3. if the user waits 2 or 3 seconds before showing the view menu everything is fine. so the problem is that much visible...

... so this is regression caused by the fix of 201494 ... to me (& based on priority guidelines) P1

The difference between the two stacktraces is:
