V.Narayanan updated DERBY-2921:

    Attachment: Replication_Network_v7.stat

Thank you for the detailed reviews and comments Oystein!

1 - I did a scan of all the javadoc in the current patch and have modified
    them to comply to the suggestions. 

2 - I have added @throws tag to all the exceptions.

3 - I have changed the Initator to accept a long do the following now,
    ReplicationMessage initiatorMsg = new ReplicationMessage
    (ReplicationMessage.TYPE_INITIATE, new Long(

    I have also changed the name of the method to sendInitiatorAndReceiveAck
    since it first sends a initiator messages and receives a ack corresponding
    to that.

4 - The method names have been changed to getHostAddress() and getPortNumber().

5 - I have made serverSocket local.

6 - The methods in SocketConnection do not cast anymore. The casts are instead
    done in the place where these methods are used.

7 - I have changed the methods to do the reset and the flush.

8 - TYPE_LOG - changed to LogRecord

    TYPE_INITIATE - uses a Long now.

    VERSION_MISMATCH has been removed.

> A network connection is required between the master and slave Derby instances of a replicated
database. The connection will be used to send many kinds of messages, including:
> * log records
> * the database (when replication is started)
> * master -> slave commands (like "stop replication")
