org.apache.bookkeeper.bookie.EntryLogManagerForSingleEntryLog#createNewLog(long, java.lang.String) createNewLog 带reason的参数方法未加锁，会存在并发调用问题，至少在SortedStorage下大概率会出现并发问题，在GC写入线程和sortedLedger写入线程、checkpoint都可能并发创建NewLog，导致并发处理log尾部的index数据：会造成数据写入错乱导致解析出错,同理造成解析log尾部index数据出错（index数据、entrySize数据、entry数据交替写入）；理论上dbLedger没有这个问题，dbLedger调用createNewLog是通过getCurrentLogForLedgerForAddEntry触发的，该方法有加锁 -- This is an automated message from the Apache Git Service.
