Michael McCandless updated LUCENE-2618:
---------------------------------------
Attachment: LUCENE-2618.patch
Patch.
I think I found this -- it's a thread safety issue, that happens when a
"normal" merge is kicking off at the same time that another thread calls
optimize.
In this case it's possible that merge fails to mark itself as an optimizing
merge, which means any merges that cascade from it will also fail to be
optimized.
I also modified MockDirWrapper to randomly call Thread.yield to see if we can
tease out any more thread bugs.
