Wolf-Dieter Fink created WFLY-7052:
--------------------------------------
Summary: unclear NullPointerException if the deployment-scanner element is
removed from the configuration
Key: WFLY-7052
URL: https://issues.jboss.org/browse/WFLY-7052
Project: WildFly
Issue Type: Bug
Components: Server
Affects Versions: 11.0.0.Alpha1
Reporter: Wolf-Dieter Fink
Assignee: Jason Greene
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}
Log message:
ERROR [org.jboss.as.controller.management-operation] (ServerService Thread Pool -- 34)
