Steve Rowe commented on SOLR-12201:
-----------------------------------
I temporarily put another assertion at the top of the failing test to make sure
that the replication failure count is zero, and it is in all the test runs I've
done; these failures are not the result of other test methods' failing to
cleanup properly.
