      Description

      While working on SOLR-9014 I came across a strange test failure.

         [junit4] ERROR   16.9s | AsyncCallRequestStatusResponseTest.testAsyncCallStatusResponse <<<
         [junit4]    > Throwable #1: com.carrotsearch.randomizedtesting.UncaughtExceptionError: Captured an uncaught exception in thread: Thread[id=46, name=OverseerStateUpdate-95769832112259076-127.0.0.1:51135_z_oeg%2Ft-n_0000000000, state=RUNNABLE, group=Overseer state updater.]

         [junit4]    > 	at java.lang.Thread.run(Thread.java:745)
      

      The underlying problem can manifest by tripping the above assert or a BadVersionException as well. I found that this was introduced in SOLR-7281 where a new 'downnode' command was added.
