Michael McCandless updated LUCENE-4147:
---------------------------------------
Attachment: LUCENE-4147.patch
Patch, acquiring the commitLock around close and rollback, and adding
the ensureOpen before prepareCommit. However, the test still fails
after a few hundred beasting iterations, I think because of thread safety
issues where one thread calls docWriter.abort while another is
flushing ... not sure how to fix that one yet. Simon maybe you can
have a look?

> rollback should never throw this exception, as it documents it clears any
> pendingcommits.
> but it calls closeInternal outside of any sync block, so it looks like there
> is a race here.
