Hi oVirt Engine developers, I've just merged a patch to bump oVirt Engine's JUnit requirement to the latest available 5.1 GA. As a first step, I've integrated the vintage engine, which is a drop-in replacement that can run old JUnit 4 (and even JUnit 3!) tests, just with a newer runtime engine. This isn't the final goal, but a first step towards moving to the newer Jupiter engine, which won't be a clean dependency replacement. Please let me know if you encounter any problem. Regards, Allon
