com.sun.messaging.jmq.util.txnlog.file.FileTransactionLogWriter
This class is used to write FileTransactionLogRecord to the transaction log file.
Each transaction is written as a transaction log record. Each record written is synced to the disk. Broker does not need to sync its message stores until a check point request (CheckPointListener is called).

        synch = false;
      }
      logger.log(Logger.INFO, br.getKString(BrokerResources.I_OPEN_TXNLOG,
            mode, Long.valueOf(filesize.getBytes())));


      FileTransactionLogWriter ftlw = new FileTransactionLogWriter(
          rootDir, filename, filesize.getBytes(), mode, synch,
          isTxnLogGroupCommits,
          BaseTransaction.CURRENT_FORMAT_VERSION);
      long existingFormatVersion = ftlw.getExistingAppCookie();
      
      // 
      // Check version here
      // if(existingFormatVersion!=BaseTransaction.CURRENT_FORMAT_VERSION) 
      // then file may need to be converted.
