[jira] [Updated] (AMQ-4997) Dead code in VMTransport class

     [ https://issues.apache.org/jira/browse/AMQ-4997?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Yuriy Sidelnikov updated AMQ-4997:
----------------------------------

    Description: 
The object with name DISCONNECT is created as 
private static final Object DISCONNECT = new Object();

so it can't be modified or be overwritten somewhere outside this class.

However this object is used only two times to check if:
public void doDispatch(VMTransport transport, TransportListener transportListener, Object command) {
        if (command == DISCONNECT) {
            transportListener.onException(new TransportDisposedIOException("Peer (" + peer.toString() + ") disposed."));
        } else {
            transport.receiveCounter++;
            transportListener.onCommand(command);
        }
    }

and 
if( command == DISCONNECT ) {
                tl.onException(new TransportDisposedIOException("Peer (" + peer.toString() + ") disposed."));
            } else {
                tl.onCommand(command);
            }
so only one branch of ifs will be run.
Seems as some remnant of modification?
