  • Constructor Details

  • Method Details

    • setChannelExtMsgCoder

      public void setChannelExtMsgCoder(Open remoteOpen)
      Set the extend message coder for current channel. The reason for separating this part from constructor is, in #channel.pipeline().replace(..), the invokeChannelRead() will be invoked after the original message coder handler got removed. And there is chance that before the session instance is fully initiated (constructor returns), a KeepAlive message arrived already in the channel buffer. Thus #AbstractBGPSessionNegotiator.handleMessage(..) gets invoked again and a deadlock is caused. A BGP final state machine error will happen as BGP negotiator is still in OPEN_SENT state as the session constructor hasn't returned yet.
