I'm trying to use Spring AOP to intercept methods of my GWT-RPC application (using GWT-Server library, so RPC service doesn't extend RemoteServiceServlet). When I deploy my war to tomcat and start the application, CGLIB fails for some reason. But I don't understand why CGLIB is being used for proxying at the first place. Since my RPC class implements the interface, shouldn't it be using JDK dynamic proxies? Does my interface need to be a spring bean for that?
Is there anything I need to do to debug this issue? Kindly advise.
Note: FYI, Spring encounters this exception, but I believe that's a different problem, I'm unable to understand why CGLIB proxy is in the picture.

or do one of following:
1. Use one of the CacheManager.create() static factory methods to reuse same CacheManager with same name or create one if necessary
2. Shutdown the earlier cacheManager before creating new one with same name.
