I don't think we intend to support marshalling Java objects. It could be implemented using Serializable, but for now it is not implemented at all. Until it is, perhaps the error messaging should be better.

Ok, I was mistaken, this is implemented . The question is, what is Java::Null doing?

As far as I can tell, Java::Null is a random synthesized Ruby module. So the problem is that you have a cycle like this:

Marshal -> Serialize -> Marshal

Even though our IRubyObject objects implement serialization, they may not be fully serializable. This appears to be the case. jcodings objects aren't serializable.

I made a slight improvement to error messaging in d915e342.
