Alan Woodward commented on SOLR-9426:
-
There are two Exceptions that get thrown here, the "can't write
replication.properties twice" one above (which is enforced by
MockDirectoryWrapper, and so won't actually cause problems outside tests) and a
"failed to close IndexWriter" one. The latter is the one that occasionally
causes test failures, although sometimes it just gets swallowed silently - I'm
not entirely clear why, but it makes reproducing these very tricky. The
IndexWriter closure failure is because on reload, SolrCore tries to remove old
index directories, but it does this before closing the old IndexWriter, which
tries to execute a rollback on its uncommitted data.
