Hello,
We are running into a problem concerning the EJB 3.x timer service. We are noticing the timer doesn't fire timeouts anymore after an exception has occured and the retry of the current timeout isn't finished before the new timeout should occur.
We attached two source file, which will demonstrate the problem.
In short:
The execute method in the attached example gets called every minute. The first time it will throw an exception to enter the retry. When entering the retry it will sleep for 90 seconds to make sure it is not finished before the next timeout occurs.
After the retry finished, new timeouts will not occur. We would expect new timeouts after the retry finished, but this doesn't happen. Can anyone explain why?
We run the example on:
- JBoss 6.0
- with JRE 1.6.0_26
Below you will find the logging:
