Sorry. I didn't read the code carefully.
I believe you could provide simple wrappers for these objects that conform
to the bean standard. These would forward/delegate all method calls to the
*real* object's methods/properties but provide the desired property change
events. Obviously, methods which have side effects would require
notification support from the underlying legacy non-bean.
A little wrapper code may be worth the tradeoff for cleaner rules and would
allow for migration away from the legacy interfaces.
This requires that you to have control over how your instances get created
so that you can inject the wrappers. Depending on your context, this may not
be possible.
Good luck!
