ClassNotFoundException: com.sun.jini.mahalo.TxnMgrProxy$ConstrainableTxnMgrProxy

Environment -
Jini 2.1
Java 1.6.0_03
Eclipse 3.4
WinXP SP2

I am attempting to run the Compute Farm appication using the example "SquaresJob"

It runs fine if I just use the in-memory SimpleJobRunner, but when I actually attempt to use JavaSpaces it complains that it cannot load:

java.rmi.ServerException: RemoteException in server thread; nested exception is:
    java.rmi.UnmarshalException: unmarshalling method/arguments; nested exception is:
    java.lang.ClassNotFoundException: com.sun.jini.mahalo.TxnMgrProxy$ConstrainableTxnMgrProxy
    at net.jini.jeri.BasicInvocationDispatcher.dispatch(BasicInvocationDispatcher.java:644)

Which is completely bizarre because just previous to this the log output (line 35) stated that it was returning com.sun.jini.mahalo.TxnMgrProxy$ConstrainableTxnMgrProxy.

A positive attitude may not solve all your problems, but it will annoy enough people to make it worth the effort.

Is this the full stack trace?

Which process is issuing this exception? Is it the JavaSpace?

If I had to guess at this stage I would say that some process is
attempting to download the code for the proxy and can't. Which points
to a codebase access problem which could be firewall, messed up codebase
URL, or messed up networking or a configuration problem.
