> `jdk.lambda.vm.InterfaceAccessFlagsTest` uses `ClassToInterfaceConverter` to mechanically convert a classfile for a Class into an in-memory class representation of an equivalent Interface.  `testPrivateMethodCall`  tests to invoke a private method. Before nestmates, invoking a private class method and a private interface method both use `Invokespecial`.   With the nestmate changes, the class uses `invokevirtual` but the interface must use `invokeinterface` but this conversion is not handled by the existing `ClassToInterfaceConverter`.
