(The only way to serialize a TLR represents a strange abuse to
begin with. You'd need to save the result of
ThreadLocalRandom.current() in a field of a serialized object.
Which would be a terrible idea ...)
It does seem nonsensical. Given that the padding isn't used then the
simplest thing might be to do "nothing", meaning treat this update as an
API change that changes the serialized form. I don't see any
compatibility issues as deserialization on an older release will just
leave the padding fields with their default values (and as they are
unused then it shouldn't matter). I think this would be simplest than
adding serialPersistentFields and a writeObject to write these unused
fields.
