Uwe Schindler updated LUCENE-4245:
----------------------------------
Attachment: LUCENE-4245.patch
Here my idea of a patch, there is still a crazy test missing enforcing an
interrupt to the merge thread:
- It changes the finishMerges() in closeInternal to a loop that repeats until
the call succeeded and did not throw ThreadInterruptedException.
- After the first one was interrupted, all later invocations will pass
waitForMerges = false, so CMS shuts down ASAP (but could still be interrupted,
so we have to do this in loop).
- After loop has finished, we rethrow the first ThreadInterruptedException &
close the merge scheduler for safety.
> IndexWriter#close(true) should either not be interruptible or should abort
> background merge threads before returning
