I had to fudge it for the release and will unfudge after the release.

The test tests if a labeled exception is uncaught by inner unlabled handler and is caught by
outer labeled handler instead, but on JVM it's uncaught entirely.

Fudge: https://github.com/perl6/nqp/commit/0994e33818

Output of failing test:

I have committed https://github.com/perl6/nqp/commit/59d7a8869c and this test passes now.

As far as I understand, the right handler was missed when moving to the outside, because unwind_check sets the outer handler to 0 by default if no outer handler is passed. We do the latter now.

I'm closing this ticket as 'resolved'.
