Using RPCs to distribute jar files is still the quick hack from the very
early days of the project. I've already fixed this issue on several branches
but I guess the change did not make it to the upstream code. I could offer to
take care of this problem, either through some sort of HTTP transfer or by
leveraging the distributed file system.
