-----------------------------------

             Summary: java.lang.NullPointerException: Null key
                 Key: NETBEANS-5014
                 URL: https://issues.apache.org/jira/browse/NETBEANS-5014
             Project: NetBeans
          Issue Type: Bug
          Components: javascript - Editor
    Affects Versions: 12.2
         Environment: Product Version: Apache NetBeans IDE 12.2-rc1
Java: 14.0.2; Java HotSpot(TM) 64-Bit Server VM 14.0.2+12-46
            Reporter: Czukowski


Not sure what exactly did I do to trigger this, I edited a file that had some HTML code in it and after a while I noticed this error notification icon. I haven't noticed an error like this in 12.1 so I assume it's probably new.

The exception seemed to have no effect on IDE stability.
