Review Comment: Yes, it's hardly to see two `BitSetRecyclable` objects share the same underlying long array (`ackSet`). In this case, even if two allocations of `BitSetRecyclable` share the same slot in the recycler's local pool (`Recycler#threadLocal`), the long array is still allocated twice from JVM heap memory, which should take the majority of the memory. ---- The change is done, PTAL again @dao-jun -- This is an automated message from the Apache Git Service.
