But wouldn't there be an issue with JDK7 TLR streams being deserialized by JDK8, pad fields would be left in the Object input steam? If so, then we're down the road of having to have a readObject, etc... and possibly back to serialPersistentFields? Technically deleting fields is an incompatible change as the stream will not contain the fields. If someone is crazy enough to serialize with jdk8 TLR and send it to a jdk7 release then the fields will have their default value (as the values aren't in the stream). As the fields aren't used then I don't think this should make a difference. Going the other way shouldn't be an issue either as the pad fields will be ignored. -Alan. Should there also be a change/patch to JDK7 TLR that would "fix" the strange behaviour (by adding readResolve)? This would align the semantics no matter which direction (7/7, 7/8, 8/7, 8/8) of serialization/deserialization is used...
