I'm not sure. The only other bug we know about is that Hessian 4 has a problem in BigDecimal serialisation. But I can't see that in the stack trace.
I'm currently deciding what to do about Hessian. Options include moving to something other than Hessian or forking Hessian since upstream isn't accepting patches. In the meantime, if you hit the BigDecimal bug, it isn't hard to work around.
