Subject Re: EXT :Re: Message Priority In 5.5.0-fuse-00-43

so that is not expected. Have a peek over one of the message priority
test cases to see if there is something different from your scenario,
you need to enable priority support on a destination for example.

Also note that kahaDB supports three priority levels, and the jdbc store 0-9.
