             Summary: Intermittent NPE when removing data sources
                 Key: WFLY-5023
                 URL: https://issues.jboss.org/browse/WFLY-5023
             Project: WildFly
          Issue Type: Bug
          Components: Server
    Affects Versions: 10.0.0.Alpha6
            Reporter: Jan Martiska
            Assignee: Brian Stansberry


When removing a datasource, sporadically this exception appears in the log:
{noformat}
12:49:58,224 WARN  [org.jboss.msc.service.fail] (MSC service thread 1-8) MSC000004: Failure during stop of service org.wildfly.data-source.ds51: java.lang.NullPointerException
	at org.jboss.as.connector.subsystems.datasources.AbstractDataSourceService.stop(AbstractDataSourceService.java:161)
	at org.jboss.msc.service.ServiceControllerImpl$StopTask.stopService(ServiceControllerImpl.java:2056)
	at org.jboss.msc.service.ServiceControllerImpl$StopTask.run(ServiceControllerImpl.java:2017)

	at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617)
	at java.lang.Thread.run(Thread.java:745)
{noformat}

This doesn't seem to happen on WildFly 9.x, only on recent master.
I suspect that this could lead to some resource leaks, but didn't study it further.
