Request for ClassPath API extension.

After obtaining new usecases and requirements for ClassPath API, I have 
decided to
extend the functionality of the PathResource class by adding the 
getHandle () operation into it.
The operation should return null for transient PathResources or 
PathRsource.Handle
for persistent ones.

Change in ClassPath contract:
Instead of writing convertors directly for PathResource subclasses,  
developer needs to provide
convertor for handlers.

Solved requirement:
The client of PathResource can use handler to store a reference to 
PathResource.

Any comments are welcomed.
