Description

« Hide

If a document hits a non-aborting exception, eg something goes wrong
in tokenStream.next(), and, that document had triggered a flush
(due to RAM or doc count) then DocumentsWriter will deadlock because
that thread marks the flush as pending but fails to clear it on
exception.

I have a simple test case showing this, and a fix fixing it.
