Description

Spinning this off from SOLR-9363 where sarowe's jenkins encountered a strange test failure when TestInjection is used causing replicas to return errors on some requests.

Reading over the logs it appears that when this happens, and the replicas are put into LIR they then ignore an explicit user requested commit (ie: Ignoring commit while not ACTIVE - state: BUFFERING replay: false) but still participate in queries – apparently before they finish recovery (or at the very least before / with-out doing the commit/openSearcher that they previously ignored.

Details and logs to follow...

• relates to: SOLR-9367 TestInjection's use of a static Random means that sequences of events can be diff for the same test seed depending on wether individual methods are run, or entire test classes, or multiple classes in the same slave JVM
