Created attachment 540948 [details]
trace from catalina.out containing the IllegalArgumentException

Description of problem:
During the course of some automated testing, a call was made to refresh pools, but the jobDetail came back with a FAILED state and the results was:
org.quartz.SchedulerException: Job threw an unhandled exception. [See nested exception: java.lang.IllegalArgumentException: attempt to create delete event with null entity]

I have not seen this before I am not yet sure about a recreate scenario.  Nevertheless, I am opening a bug with some logs.  Maybe you can decipher the scenario.  Starting with the automated test logs, it looks like a POST was made to create a subscription followied by a refresh pools call:

201112040341:24.078 - INFO: ======= Starting Test: VerifyPoolIsNotYetAvailableUntilTheStartDate_Test (com.redhat.qe.auto.testng.TestNGListener.onTestStart)

Then the jobDetail from the refresh pools PUT call was:

and the catalina.out log containing the IllegalArgumentException stack trace is attached.
