I pushed two unit tests in the fxml repo. They're green thanks @Ignore but run #66 exhibits the failures: http://jfx.sfbay.sun.com/hudson/job/presidio-fxml-sandbox/label=windows-i586-14/66/console
There's something vicious in the fact if you run the test on only the test flagged as "faulty" then it might pass: it's only because there's plenty of FXMLLoader.load() calls that are done that at some point some of them fail.
