Description Stephan Herrmann CLA 2016-09-04 05:49:57 EDT 
While setting up a workspace for BETA_JAVA9 work a clean build of org.eclipse.jdt.core gives exceptions like the following:

org.eclipse.core.runtime.CoreException: Unable to resolve superclass java.lang.Enum for javax.lang.model.element.ElementKind

I'm running on Neon SDK + API descriptions + Beta Java 9 patch from the Market Place.

Am I missing anything?

Possible fix.

I need to investigate possible repercussions of this patch.
Comment 2 Vikas Chandra CLA 2016-09-08 06:29:24 EDT 
This problem happens in latest oxygen as well.
Comment 3 Vikas Chandra CLA 2016-10-17 01:44:59 EDT 
Now it doesn't happen anymore. I tried various builds.

Stephan, does this problem exist for you now. Please specify the Y build id if this problem recreates.
Comment 4 Vikas Chandra CLA 2017-03-15 09:54:55 EDT 
I haven't seen this problem in last 2-3 months.
