How is the EchoServer instance being exported?  If it is exported by
invoking the static UnicastRemoteObject.exportObject(Remote) method,
then a pre-generated EchoServer_Stub class is still required
(regardless of the java.rmi.server.ignoreStubClass system property
setting); for more information, see:

http://archives.java.sun.com/cgi-bin/wa?A2=ind0501&L=rmi-users&P=556

The fix is to use the UnicastRemoteObject.exportObject(Remote,int)
method instead, passing 0 for the port.

Note that the exception quoted above seems to indicate that an
EchoServer_Stub class was actually found and instantiated in the
remote object's VM; it just couldn't be found during unmarshaling in
the registry's (?) VM.
