There are a couple of hiccups when using the jtreg plugin on the latest 2016.3 idea:

* the signature of AntConfiguration.getAntBuildFIles changed as a result of a refactoring (the return type is more specific).

* the method 'isSmRunnerUsed' has been removed from JavaTestFrameworkRunnableState and therefore the @Override annotation should be removed (but method should be kept for compatibility with earlier versions).
