[GitHub] [rocketmq] RongtongJin commented on issue #2023: no use to create byteBufferNew in function MappedFile#selectMappedBuffer(int pos)

   I think it is necessary to create. Although byteBuffer and byteBufferNew share the same content, the values of position, limit, and mark are independent. For example, byteBuffer current position is pos, byteBufferNew is 0.
