This can be easily used for crashtesting (filtering out only tests with jvm crashes).

I believe that this approach is pretty minimalistic when all the capabilities for the user are taken into account and presents almost no maintenance overhead. Plus the user of the jtreg project is someone who should know what he is doing and giving him tools to peek inside and modify the test evaluation behavior is nothing bad IMO. Default behavior of jtreg release is also not affected by this change.
