Of course at first generated proxies were not able to find CGLib, since bundle class loader of the mail bundle does not see classes that are part of a webapp.
No, it is not clear why JavaMail classes looked for CGLib classes. Do
you have the exception stacktrace?

When you define new classes using CGLib, which class loader do you use?
If you use the class loader used to load CGLib classes, then the proxy
can't locate JavaMail classes. I don't know how CGLib works, but I would
try adding CGLib to war file or ejb-jar and define the proxies using
Thread's context class loader. Give it a try if you have not.

No, you can't override Platform APIs using lib/ext or any such
technique. Even if you did something like this in v2, that was not a
supported configuration.
