maybe a little problem of Message class.

why use this.offset as start point instead of this.offset+this.length

java-nio-server/src/main/java/com/jenkov/nioserver/Message.java

Lines 92 to 97 in 35fdd0f

	public void writePartialMessageToMessage(Message message, int endIndex){
	int startIndexOfPartialMessage = message.offset + endIndex;
	int lengthOfPartialMessage = (message.offset + message.length) - endIndex;
	System.arraycopy(message.sharedArray, startIndexOfPartialMessage, this.sharedArray, this.offset, lengthOfPartialMessage);
	}

I am confused by this line as below:
int startIndexOfPartialMessage = message.offset + endIndex;
I think it should be int startIndexOfPartialMessage = endIndex+1 ,because message.offset and endIndex are both address in shareArray And the next partial message index should be endIndex+1 if exists.

    public void writePartialMessageToMessage(Message message, int endIndex) {
//        int startIndexOfPartialMessage = message.offset + endIndex;
        int lengthOfPartialMessage = (message.offset + message.length) - endIndex;
        if (lengthOfPartialMessage > 0) {
            int startIndexOfPartialMessage = endIndex + 1;
            System.arraycopy(message.sharedArray, startIndexOfPartialMessage, this.sharedArray, this.offset, lengthOfPartialMessage);
        }
    }
