unclear NullPointerException if the deployment-scanner element is removed from the configuration

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:

{xml}
<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>{xml}
