Michael McCandless commented on LUCENE-3855:
--------------------------------------------
Thanks Dawid! I'm not sure LUCENE-3857 is what I'm hitting (this test doesn't
have a @beforeClass).
One more piece of data: sometimes the CMS exception *is* printed in the
"unhandled exceptions" output... so it's somehow intermittant. Hmm, it could
be... the main thread threw its exc before CMS thread did? Odd, though,
because IW closes CMS first (which should join to all outstanding threads),
before hitting the exc in main thread. Still baffled...
Anyway it's not a blocker for me... I'm printing the exc in CMS.handleExc.
