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?

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.

I haven't seen this problem in last 2-3 months.
