Basically, we have a couple of failures in the AS testsuite when running some tests under the Java security manager.

The exception looks as follows:
Caused by: java.security.AccessControlException: access denied (javax.management.MBeanPermission org.jboss.ejb.txtimer.EJBTimerServiceImpl#getTimerService[jboss.ejb:service=EJBTimerService] invoke)

Please add privileged blocks around the lines:
TimerService timerService = service.getTimerService(containerId, id);
and
service.removeTimerService(containerId, id);

Assign it back to me, if you need help.
