    Description

      Seen in our clustering failover tests for remote stateful EJBs.
      Setup: 4 node cluster, one node at the time is shut down gracefully, while 2000 standalone clients keep calling the application.

      During the graceful shutdown, 2 servers logged this error message right after stopping the deployment:

      [JBossINF] �[0m�[33m05:27:23,973 WARN  [org.infinispan.transaction.impl.TransactionTable] (ServerService Thread Pool -- 81) ISPN000100: Stopping, but there are 0 local transactions and 28 remote transactions that did not finish in time.

          Bug - A problem that impairs or prevents the functions of the product. JBEAP-13743 EJBCLIENT000509: Unexpected exception processing EJB request: NPE during server graceful shutdown

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
