> The current model tries to isolate each extension and the application to 
> their own classloader.  This works ok until there is a need to share objects 
> between them.  At this point these object's  classs are each loaded by 
> seperate classloaders. Classes loaded this way don't work well.  For example, 
> a class creating an instance by one classloader in an extension and then 
> passed to an application that has the same class loaded by another class 
> loader will see a classcast exception when an attempt is made to set a 
> reference to the passed in object.
> Currently an example of this  happens with databinding framework when using 
> SDOs.  The application creates SDOs loaded by its classloader.  When the SDO 
> object is sent on the wire the databinding framework intercepts to attempt to 
> convert SDO to axiom for a webservice interface.  But SDO classes in the SDO 
> databinding framework are loaded via another classloader.
