I have a store of serialized objects, created using JDK1.2.2. When I attempt to
read the objects from the store using JDK1.3RC1, I get the following exception:

java.io.InvalidClassException: java.util.Collections$SynchronizedCollection;
Local class not compatible: stream classdesc
serialVersionUID=3053995032091335093 local class
serialVersionUID=7487094791527871196

A class inside the collections within java.util has been modified but the serial
version UID has not been set to the previous version.

======================================================================

The following non-abstract serializable classes had a different
SUID in the previous release (JDK1.2.2) and these also need to be fixed.
