----------------------------------------
There may be an issue with AMQ, TCK is puking up a bunch of things like:

> Weed out backport-util-concurrent usage for server/trunk
> --------------------------------------------------------
>
> Key: GERONIMO-2995
> URL: https://issues.apache.org/jira/browse/GERONIMO-2995
> Project: Geronimo
> Issue Type: Improvement
> Security Level: public(Regular issues)
> Affects Versions: 2.0
> Reporter: Jason Dillon
> Assigned To: Jason Dillon
>
> Now that server/trunk requires 1.5 to build and run, I think we should start
> to weed out our usage of the {{backport-util-concurrent}} library (and
> concurrent if there is still anything left of that in our src tree).
> I think we may still have to include {{backport-util-concurrent-\*.jar}} in
> the assembly until all of our dependencies have weeded it out too... or
> perhaps just have to live with that in the repository. But hopefully we can
> remove our usage of these classes and not need to include this puppy in
> {{lib/\*}} anymore.
> Looks like we are currently using {{edu.emory.mathcs.backport}} in 39
> locations (based on imports) which are over 25 files.
> Even after weeding out *our* usage, if we still need to include this jar I
> recommend we update to the latest release 3.0.
