It's supposed to use the value of serialVersionUID if the class has a
field of that name, and compute a default value if serialVersionUID is
not explicitly specified.  See the section titled "Stream Unique
Identifiers" in the Java Object Serialization spec (included with the
JDK 1.1 docs), which specifies what gets hashed to produce the default

(If this is what's going wrong, then specifying an explicit
serialVersionUID for all the serializable classes involved in the RMI
test may work around the problem.  This is a god idea in the long run
anyway, to control interoperability in the face of version skew ---
see the section on versioning in the Object Serialization spec).
