Subject [jira] [Commented] (AMQ-6065) Allow selective use of broker systemExitOnShutdown from DefaultIOExceptionHandler
Date Mon, 30 Nov 2015 12:54:11 GMT


Christopher L. Shannon commented on AMQ-6065:

Ok, no problem.  I was thinking it would be ok because it's just a test dependency and wasn't
being included with the release, plus it is the same license as older version of JUnit.

As soon as you are done I will start the release process for 5.13.0.

> the broker attribute systemExitOnShutdown is useful in a karaf container or shared vm
where the broker is the primary occupant. If the broker dies, then the container should die.
> For the broker, if the store dies, then the broker should die, but for other scenarios,
like the broker is shutdown via jmx or for maintenance, exiting the container is not required.
> Allowing the DefaultIOExceptionHandler, which gets to handle store exceptions, flip the
systemExit bit allows a container to exit on this fatal condition. Ensuring that failover
of the store can occur due the the exit of the jvm that has the store lock.
> With karaf on windows, the file locker is not reliable on failback when the jvm remains
