> The problem essentially seems to be that the leading $ of the class name
> (e.g. '$Proxy5') confuses the annogen and adb library. I found two problems,
> one in org.codehaus.jam.internal.JamClassLoaderImpl and one in
> org.apache.axis2.databinding.utils.BeanUtil. I found workarounds to the
> problems by explicitely checking for Proxy classes. I am actually not sure
> that this is the right way to fix the problem. Anyway, I'll attach them to
> this issue for reference.
