I have a problem sending strings over RMI. I run a client that passes
over a string via RMI to a server. The server does nothing except
returning the same string. It works fine if the server is run on a Sun
VM. Using JamVM (or Kaffe) with GNU Classpath leads to exceptions on the
client side if the strings are longer than 65535 (ASCII) characters. The
following exception is caused:
Client exception: java.rmi.MarshalException: error marshalling
arguments; nested exception is:
java.net.SocketException: Broken pipe

Returning Strings with more than 65535 characters from the JamVM/Kaffe
server makes server and client hang (no further inspections made so
far). I guess it's some 16-Bit limitation of the marshalling. Can anyone
confirm this?
