I could not recreate this uitests error, at least not when running the org.openjdk.jmc.test.jemmy project standalone. I would try to get clean tests and uitests on all my dev machines after the refactoring (also in application) is in.

As for copyright years: I would think if files are only moved around without changes, one doesn't need to modify the copyright years. That's at least my experience from OpenJDK. Please let me know what you'd prefer.
