    Description

      AsyncWriter of FSHLog might throw ArrayIndexOutOfBoundsException because of the following code in AsyncWriter#run():

                   }
                 }
                 if (!hasIdleSyncer) {
                  int idx = (int)this.lastWrittenTxid % asyncSyncers.length;
                   asyncSyncers[idx].setWrittenTxid(this.lastWrittenTxid);
                 }
               }
      

      In obove code, "this.lastWrittenTxid % asyncSyncers.length" might become negative when this.lastWrittenTxid is bigger than Interger.MAX_VALUE where this.lastWrittenTxid is a long. The attachment gives a quick fix.
