> Could you please elaborate why the Set does not work? We are using set because of we do observe the list operation can cause a huge delay in computation for other scenarios. > > Unless we have a strong reason using List or clear drawback for Set, I prefer to keep the set. Please refer to https://stackoverflow.com/questions/2265503/why-do-i-need-to-override-the-equals-and-hashcode-methods-in-java, we are not using it right. Two "equaled" object will be hashed into different bucket (or with collision, same bucket). There is no point using set over list in our case if `hashCode` isn't overriden. -- This is an automated message from the Apache Git Service.
