LUCENE-4737: be more verbose and print stdout/stderr when a nested test fails.
I suspect all these are related to thread leaks on J9 which I cannot reproduce
but this should reveal the cause of the problem.

> Key: LUCENE-4737
> URL: https://issues.apache.org/jira/browse/LUCENE-4737
> Project: Lucene - Core
> Issue Type: Bug
> Reporter: Michael McCandless
>
> Curiously, the tests only seem to fail when I run "ant test" from
> lucene/core. No "Reproduce with" line is printed ... and if I run the
> failing tests alone, they do not fail.
