When converting back from our internal form to a classfile for the JVMTI RetransformClasses agents, I need to either filter the interface out if we injected it or not if it was already there. JVMTI's GetImplementedInterfaces call has a similar issue with being consistent - and that's really the same issue as reflection. There's a lot of small places that can easily become inconsistent - and therefore a lot of places that need to be checked - to hide injected interfaces. The easiest solution to that is to avoid injecting interfaces in cases where javac can do it for us so the VM has a consistent view. I think you may be envisioning extra complexity that isn't needed here. The plan of record is that we *won't* hide injected interfaces. Our hope is that the implicit/explicit distinction is meaningless—that turning implicit into explicit via JVMTI would be a 100% equivalent change. I don't know JVMTI well, so I'm not sure if there's some reason to think that wouldn't be acceptable...
