Comment 3 Tomas Pavek 2015-10-02 09:36:49 UTC 
As explained in bug 245600, this is a bug in com.jidesoft.plaf.vsnet.VsnetMenuUI, which is some 3rd party garbage, not standard part of NetBeans IDE. It breaks into every menu item creation and calls getPopupMenu on not yet initialized menu. Asking for popup menu creation in setUI is evil.

Given the high number of reports and pretty serious impact (unusable GUI builder) this probably deserves a workaround.
Comment 4 Tomas Pavek 2015-10-02 12:43:30 UTC 
Applied a workaround that should help, though not able to verify. The workaround is simple and safe.

Comment 6 Jiri Kovalsky 2015-10-02 13:24:58 UTC 
OK, the fix seems safe. Please integrate the fix to release81 branch.

Integrated into 'main-silver', will be available in build *201510030002* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
