I've started implementing jewelcli and I like it so far, but I've ran into an issue.

Any ideas on this as right now I'm clueless?

This might be a difficult one to sort out as it is probably related to how
your container is behaving. I am not familiar with the minecraft server.
However it is possible that this is a bug in JewelCli - I had not
considered the case of someone using it in a server with isolated
classloaders.

The error says, I think, that the classloader that loaded the .class that
you passed into CliFactory is not the same as the classloader available via
Thread.currentThread().getContextClassLoader().

I may be able to fix it by using the classloader of your interface to
create the dynamic proxy instead. Let me try to build a new version for
you...
