I've added a timer service in one of my ejb of a specific module inside my ear application through the @Schedule annotation.

I then removed the method annotated with the Schedule annotation and redeploy.

The AS refuses to deploy my module (and my entire ear as a consequence) ended up with the following exception:

Caused by: java.lang.IllegalStateException: JBAS014478: Could not find timeout method: com.acme.AppLogger.processSend(javax.ejb.Timer)

at org.jboss.msc.service.ServiceControllerImpl$StartTask.run(ServiceControllerImpl.java:1746) [jboss-msc-1.0.2.GA.jar:1.0.2.GA]

I add to get rid of the $JBOSS_DIR$standalone/data/timer-service-data folder to be able to properly redeploy.
