Aw: Strange test failures: validation of PGGroup children failed

[Marius Hanl]

   I think I had the same issues some days ago. What helped was to delete
   all the 'build' or 'target' or 'out' folders - so basically all the
   folders with the compiled files.

   Betreff: Strange test failures: validation of PGGroup children failed
   Just stumbled across it while reviewing PR 719
   ([1]https://github.com/openjdk/jfx/pull/716)
   - added the new test method to see it fail (which it does)
   - run all control tests throws the error below in _unrelated_ tests
   (the one below is from TableCellTest, that is the same test the new
   failing method resides in, but seeing similar in other tests that use
   Toolkit.firePulse)
   Still happens after a clean build from gradle (clean, sdk,
   :controls:test).
   Any idea what might be the reason?
