David Smiley commented on SOLR-17435:
-------------------------------------
I commented an update to SOLR-17414. I characterized that JIRA issue such that
it's fundamentally wrong to throw a RejectedExecutionException for
multi-threaded search. The stack trace you share here for TestStressReorder is
the same use-case. Fixing it as I proposed would not yield such an exception.
