Please ! Do not reverse ObjectInputStream from Classpath it is really
buggy. I will fix the Serialization/RMI
problem asap using the new logic. In fact I added resolveClass(String)
to be a little quicker but as it seems
it is breaking things I will fall back to a standard behaviour.
Serialization in Classpath is not clean
at all for serialization.
P.S.: I was out today so I did not make so much work.
