Description

My Jenkins found a reproducing seed - though note that in order to reproduce I had to a) run the test at the same SHA as the one listed, and b) leave off -Dtests.method=test_dv_stored; under those conditions it failed both times I ran it:

Issue Links

• is broken by: SOLR-9366 replicas in LIR seem to still be participating in search requests
• is broken by: 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
• relates to: SOLR-9159 add some cloud based concurrent atomic updates testing
