> I saw this while writing a test case for SOLR-9438. The collection1 collection which
was in stateFormat=2 was somehow caching the CloudSolrClient's ZkStateReader such that the
returned cluster state contained the collection state. However this collection was neither
watched nor lazy so any call to waitForRecoveriesToFinish would see stale state and loop until
timeout.
