0N/A * This class implements {@link WildcardType WildcardType} compatibly with the JDK's
0N/A * {@link sun.reflect.generics.reflectiveObjects.WildcardTypeImpl WildcardTypeImpl}.
0N/A * Unfortunately we can't use the JDK's
0N/A * {@link sun.reflect.generics.reflectiveObjects.WildcardTypeImpl WildcardTypeImpl} here as we do for
0N/A * {@link sun.reflect.generics.reflectiveObjects.ParameterizedTypeImpl ParameterizedTypeImpl} and
0N/A * {@link sun.reflect.generics.reflectiveObjects.GenericArrayTypeImpl GenericArrayTypeImpl},
0N/A * because {@link sun.reflect.generics.reflectiveObjects.WildcardTypeImpl WildcardTypeImpl}'s
0N/A * constructor takes parameters representing intermediate structures obtained during class-file parsing.
0N/A * We could reconstruct versions of those structures but it would be more trouble than it's worth.
