At work but I figured out interfaces. Basically ITABLES for classes will have a key and method pointer for the implimented method. They will always be sorted. For any invocation type that is done on interfaces, it will use an INATID. The class ITABLE will be sorted INATID+METHODPTR pairs. INATID will be a unique ID derived from method name and type, but not the class type. Since if two different interfaces implement the same method. They are the same. Hence no classes. The run-time pool index will be the INATID. Then interface calls will refer to that in the JVM interface lookup. Sorting will make scanning faster. And not using classes in INATID will make there be less IDs used.
