In topic with log compaction the incorrect handling of lengthRemain into readMessageV2 lead to endlessly reading of the same compacted batch. It is happens because skipping offset to batch.lastOffset assumes that lengthRemain ==0 but without this correction lengthRemain became negative and comparison with zero doesn't work.
