Hmm. I'm not exactly sure this is a bug.
Since Hessian is a cross-language protocol, it needs to have a
consistent date representation that will work for all languages. In
other words, it can't just serialize the Java fields for java.util.Date,
but needs to turn that date into a Hessian primitive bytecode.
That does mean that a class extending java.util.Date is a problem
because there's no natural Hessian representation for that object.
