@Test public void testObjCObject() {

ToNative only has to get the ID, so it only has to know about ObjCObject
    ObjCObjectTypeConverter toNativeConverter = (ObjCObjectTypeConverter) typeMapper.getToNativeConverter(NSNumber.class);
ertTrue(toNativeConverter.convertsJavaType(ObjCObject.class));
FromNative needs to know the actual type so that it can create the right Java subclass of ObjCObject
CObjectTypeConverter fromNativeConverter = (ObjCObjectTypeConverter) typeMapper.getFromNativeConverter(NSNumber.class);
ertTrue(fromNativeConverter.convertsJavaType(NSNumber.class));
