      If the deployment scanner element is removed from the configuration of the standalone server a NullPointerException is logged which is unclear and difficult to find as the stack does not show any hint.

      Config:

              <subsystem xmlns="urn:jboss:domain:deployment-scanner:2.0">
            <!-- deployment-scanner path="deployments" relative-to="jboss.server.base.dir" scan-interval="5000" runtime-failure-causes-rollback="${jboss.deployment.scanner.rollback.on.failure:false}"/ -->
        </subsystem>

      Log message:

      ERROR [org.jboss.as.controller.management-operation] (ServerService Thread Pool -- 34) WFLYCTL0403: Unexpected failure during execution of the following operation(s): []: java.lang.NullPointerException
