Issue Type: Bug
Components: remote proxy
Affects Versions: 2.1.1

Hi,
we use Archiva version 2.1.1, and have serious errors. We get randomly but
several times Server Error 500 if we are getting artifacts from the
repository. In the archiva logs I see a lot of such errors:
java.util.

Is this a configuration problem, or a bug in the archiva code?
