We will have to clean these references during undeployment, or to use SoftReferences testing for Null Object. I think the JVM doesn't make any internal references to the created proxy, what means the Proxy will released if a GC happens. On JBoss Serialization, I created a package called PersistentReference that encapsulates such thing. It's really simple. If we want to cache proxies without having to worry on clearing references later maybe we should implement a similar idea.
