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*.

Surely the Germans, who gave us "schadenfreude" and "weltschmertz", have a
term for "the uneasy semi-certainty that one's assertion is soundly backed
by a long-forgotten source." - unknown

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