Description

On startup an error notification is displayed. "Unexpected Exception, Priority: silent, Category: Error, Show and report Problem to Netbeans Team,  Window must not be zero.

 

Netbeans 10. 

java version "10.0.1" 2018-04-17
Java(TM) SE Runtime Environment 18.3 (build 10.0.1+10)

If Starting from the command line I see:

scott@scott-Qosmio-X70-A ~/Netbeans-10.0/bin $ ./netbeans
WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.netbeans.core.windows.view.ui.MainWindow (jar:file:/home/scott/Netbeans-10.0/platform/modules/org-netbeans-core-windows.jar!/) to field sun.awt.X11.XToolkit.awtAppClassName
WARNING: Please consider reporting this to the maintainers of org.netbeans.core.windows.view.ui.MainWindow
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release

 

The IDE at this point is useless, I can edit files but cannot access any menu item either through the mouse of hot keys.

I do not see a reported exception on the command line?

If I restart it sometimes starts without the error, sometimes.

the only way to shut down the editor is by killing the java process. 

 Added 3/14:  I deleted the settings/cache folder .netbeans/10.0 so the editor could replace with new install settings, problem still persists.  

Problem is intermittent, If I see the exception I can kill the editor and restart, sometimes the first restart will work normally, sometimes it takes 2 or 3 restarts to finally get a normal start process that allows me to do my work.
