> We currently have several components with a property for specifying 
> additional classpath resources (DBCP connection pool, scripting processors, 
> JMS). Each of these components is responsible for handling this in its own 
> way. 
> The framework should provide a more integrated solution to make it easier for 
> component developers to deal with this scenario. Some requirements that need 
> to be met by this solution:
> - Multiple instances of the same component with different resources added to 
> the classpath and not interfering with each other (i.e. two DBCP connection 
> pools using different drivers)
> - Ability to modify the actual ClassLoader of the component to deal with 
> frameworks that use Class.forName() without passing in a ClassLoader, meaning 
> if a processor loads class A and class A calls Class.forName(classBName), 
> then class B needs to be available in the ClassLoader that loaded the 
> processor's class which in turn loaded class A
> - A component developer should be able to indicate that a given 
> PropertyDescriptor represents a classpath resource and the framework should 
> take care of the ClassLoader manipulation
