BUG REPORT

1. Please describe the issue you observed:

   When I read the following code about transaction messages, I noticed a problem with the method comments in class TransactionalMessageBridge.

 /**
     * Use this function while transaction msg is committed or rollback write a flag 'd' to operation queue for the
     * msg's offset
     *
     * @param messageExt Op message
     * @param messageQueue Op message queue
     * @return This method will always return true.
     */
    private boolean addRemoveTagInTransactionOp(MessageExt messageExt, MessageQueue messageQueue) {
        Message message = new Message(TransactionalMessageUtil.buildOpTopic(), TransactionalMessageUtil.REMOVETAG,
            String.valueOf(messageExt.getQueueOffset()).getBytes(TransactionalMessageUtil.charset));
        writeOp(message, messageQueue);
        return true;
    }

But in fact:

The param messageExt of the method is half message instead of Op message.
The param messageQueue of the method is half message queue instead of Op message queue.

To prove my point, I debugged the code，as shown below:

This may mislead others unfamiliar with the code's logic.
