Warnings when compiling on Fedora 17

[LionelCons]

I've compiled (mvn package) stomp-benchmark on Fedora 17 and got several warnings:

[WARNING] File encoding has not been set, using platform encoding UTF-8, i.e. build is platform dependent!
[WARNING] Using platform encoding (UTF-8 actually) to copy filtered resources, i.e. build is platform dependent!
[WARNING] warning: there were unchecked warnings; re-run with -unchecked for details
[WARNING] one warning found
[WARNING] Configuration options: 'appendAssemblyId' is set to false, and 'classifier' is missing.

You probably want to fix some of these.
