It's interesting that new InitialContext().list() returns right bound proxy classes but direct lookup invoked on the same context new InitialContext().lookup(name) returns old proxy class ... It looks like InitialContext implementation caches bound objects somewhere (in static variable?) and this cache is not cleared during re-deployment.
