Motivation:
PoolChunk maintains multiple PriorityQueue<Long> collections. The usage
of PoolChunk#removeAvailRun unboxes the Long values to long, and then
this method uses queue.remove(..) which will auto box the value back to
Long. This creates unnecessary allocations via Long.valueOf(long).
Modifications:
- Adjust method signature and usage of PoolChunk#removeAvailRun to avoid
boxing
Result:
Less allocations as a result of PoolChunk#removeAvailRun.
