      Description

      Currently, in BitmapCounter we deserialize the bitmap to get the peekLength, we know which is expensive in terms of CPU time from JMC hot code.

      Actually, we could Serialize BitmapCounter with peekLength to avoid deserializing the bitmap when we get peekLength.

      Of course, we need to keep forward compatibility.
