NPE when changing scheduled service

If I modify or remove a (persistent) scheduled service, I get the following stack trace:

Caused by: java.lang.NullPointerException
at org.jboss.as.ejb3.timerservice.TimerServiceImpl.doesTimeoutMethodMatch(TimerServiceImpl.java:959)
at org.jboss.as.ejb3.timerservice.TimerServiceImpl.restoreTimers(TimerServiceImpl.java:710)

Another user is reporting the same thing on 8.1.0 Final, see:

Is there any way using the CLI to delete persistent scheduled services?
