      1. Get a copy of EAP 7.0.0.ER6, add "repl" cache in standalone-ha.xml and set it as default:

      <cache-container name="web" default-cache="repl" module="org.wildfly.clustering.web.infinispan">
    <transport lock-timeout="60000"/>
    <replicated-cache name="repl" mode="SYNC">
        <locking isolation="REPEATABLE_READ"/>
        <transaction mode="BATCH"/>
        <file-store/>
    </replicated-cache>
    ....
</cache-container>

      2. Copy cluterbench-ee7.ear to standalone/deployments folder.
      3. Start the server with standalone-ha profile:

      Server startup command
      ./bin/standalone.sh -c standalone-ha.xml -Djboss.node.name=node1

      4. Access http://localhost:8080/clusterbench-granular/granular
      5. NPE is logged

    Description

      When default cache is set to "repl", after deploying clusterbench and accessing http://localhost:8080/clusterbench-granular/granular, the following NPE is logged:

          • Blocker - To be worked above all other priorities. This term is chosen when the severity of the issue is very high, has no workaround, or the effort for the change is comparatively low. Issues that may be very publicly visible and could generate significant media attention may also drive a higher priority.

          • 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.
