What changes are proposed in this pull request?
Use more allocated buffers instead of directly allocating new memory.
Why are the changes needed?
If the value of
BUF_POOL.ceilingEntry(length)is a empty list, removing this entry and continuing to look for the eligible buffer will reuse more allocated buffers, reducing theOutOfMemoryErrorexception caused byByteBuffer.allocateDirect.
