Re: [cross-project-issues-dev] Oxygen.1aRC1: Maven fails with org.codehaus.plexus.classworlds.launcher.Launcher when running with JDK 9

Hi,

I have not announced staging for Oxygen.1a RC2 to be complete yet.
So even though this is very late, I'd say you can go ahead and provide a
fix.

Please let me know, when you're done and the fix is committed.

Regards,

Fred
