Description

jenkins started to semi-regularly complain about ZkStateReaderTest.testStateFormatUpdateWithExplicitRefreshLazy on march 7 (53 failures in 45 days at current count)

March 7th is not-coincidently when commit 093a8ce57c06f1bf2f71ddde52dcc7b40cbd6197 for SOLR-8745 was made, modifying both the test & a bunch of ClusterState code.

...i've also seen this fail locally, but i've never been able to reproduce it with the same seed.
