Description wfink 2017-01-13 12:49:41 UTC
Description of problem:
If a calendar timer (@Schedule annotated) is renamed in the deployment class
A NullPointerException is thrown:

ERROR [org.jboss.msc.service.fail] (MSC service thread 1-1) MSC000001: Failed to start service jboss.deployment.unit."ejb31-timer.jar".component.SimpleScheduleSingletonTimerBean.ejb3.timerService: org.jboss.msc.service.StartException in service jboss.deployment.unit."ejb31-timer.jar".component.SimpleScheduleSingletonTimerBean.ejb3.timerService: Failed to start service

How reproducible:
Deploy a @Schedule timer with methodNameA.
Change the method name and deploy it again
The NPE is shown

Expected results:
Timer should be removed from persistence with a WARN message on deploy

Additional info:
If the class is deployed without any @Schedule annotation and deployed again with one (different method) the error does not appear
