Dawid Weiss commented on LUCENE-4901:
-------------------------------------
I think Runtime.halt is a very similar thing -- it (should) stop the threads
immediately without any finalization blocks/ propagation of
ThreadDeathException or otherwise. Any open file handles will be closed by the
operating system on a "real" crash so I don't think this makes any difference.
I do have native code that crashes J9 and JRockit too but this has side effects
-- J9 dumps a *lot* of debugging state information, for example. Right now
we're testing just a subset of JVMs, if the tradeoff is to increase the
coverage on other JVMs I think it's worth it to use Runtime.halt().
> TestIndexWriterOnJRECrash should work on any JRE vendor via Runtime.halt()
