getSuperSubscriberInfo always return null

[haiyang1994]

Hi, I have two question,can you tell me? ① what's the meanning of getSuperSubscriberInfo? it seems that it always return nulll.

② if B and C boths extends from A. When in findUsingInfo(Class<?> subscriberClass) in reflect, after finding the method in B, it will move to super class A and find methods in A using reflect. When it come to C, it will repeatly find methods in A using reflect. If it is more efficently to use cache.

Thanks.
