    Description

      Setup: 4-node cluster, one node at time either shuts down or undeploys application (clusterbench-ee7.ear), and then recovers after period of time, while standalone clients keep calling the application.

      This error was seen during clustering failover testing in the following scenarios:
      ejb-ejbservlet-shutdown-repl-async (failover of HTTP traffic accessing a servlet that locally invokes a stateful clustered EJB, failover type: server shutdown, with asynchronously replicated cache)
      ejb-ejbservlet-shutdown-repl-sync (the same as above, with synchronously replicated cache)
      ejb-ejbservlet-undeploy-dist-sync (failover type: application undeploy, with distributed cache which is replicated synchronously)

      It occurs in these two situations (intermittently):

      1. server startup after previous shutdown

          Bug - A problem that impairs or prevents the functions of the product. JBEAP-867 UT005023: Exception handling request: NullPointerException

          • 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.
