> The node that was the target of the {{ReplicationGroupAdmin.removeMember}} call was at that moment being restarted as majority had been lost. This seems to have provoked an unexpected exception from within JE.
> The test is concerned with ensuring the listener fires correctly in response to changes in group membership. This test can avoid the possibility of a mastership loss simply by setting designated primary to true.
> As changing the consistency of a group whilst a production system is live would be an unusual thing to do, this chances of this manifesting in production are small. If it were to happen, a node restart would be required to restore service.
