So I rather keep it here. I see. In fact, what if `byteState` is an instance variable outside the method? If a previous squeeze has left some bytes there, there is no need to call `asLittleEndian.set` again next time they are needed. Does it help in any performance gain? especially if the caller only squeeze a few bytes each time? ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/20631#discussion_r1731271264
