The object ID is the identity of an object. This is one of the basic of the
ozone object model. However, the ozone API is designed to never give this ID to
the client/programmer in order to let the ozone specific extensions to the
ordinary Java model as transparent to the programmer as possible.
There is no way to find an object by its ID because there is no (documented) way
to get the ID of an object (which is perfectly intended!).
What is the actual problem where you need to access/find objects by its ID?
Basicall ozone does nothing than finding objects by its ID. So, having an
proxy (which basically is the object ID) _is_ finding the target object.
