In a job {{eap-7x-failover-db-session-shutdown-repl-sync-postgresql}} (i.e., a REPL_SYNC failover test where sessions are stored in a PostgreSQL database, but I'm not sure how significant is that), I've seen these {{InterruptedException}}-s thrown in Infinispan during server shutdown:

Not really sure who would be interrupting the thread, but since the exceptions occur _in the middle_ of the test (the server was started again later), it's unlikely that it comes from the test environment.

Also, not sure if there's a connection to JBEAP-2436.
