Turns out, this is required by junit framework to properly handle the failed tests.

If we pass all the Throwables to the thread group, then a RuntimeException thrown from a `@Test` does not mark the unit test as failed, though the stacktrace does appear in `stderr`;  a thrown `Error` will mark the test as failed.
