Can you check whether this class is included in the classpath of each of
the member processes ? In order for your classloader in one instance to
deserialize the serialized object that another instance saved into the
cache you need to have the class in your classpath.
I wrote a small test to include your CachedData class as the object to
be stored and it works well with instances on two different machines.
