If the URLClassLoader for a class that is serialized using a MarshalledObject
is made of a files that contain spaces in their path, unmarshalling the object
fails because the space is seen a seperator between urls by the
sun.rmi.server.LoaderHandler.pathToURLs method. This is may be another
problem related to bugID 4273532?

Here is a trival example that demonstrates the problem:

Space Here 1162>ls
ASerializable.java ser.jar tstMO.class tstMO.java
Space Here 1163>pwd
/tmp/Space Here
Space Here 1164>java tstMO
cwd = file:/tmp/Space Here/./
serializable class = class java.lang.Class
serializable codesource = null
