Why a new InputStream will still read what is left over from an old InputStream?

Well please see this question and Jon Skeet's answer first.

This time I have this server:

public class SimpleServer {
    public static void main(String[] args) throws Exception {

        ServerSocket serverSocket = new ServerSocket(8888);
        System.out.println("Server Socket created, waiting for client...");

        Socket accept = serverSocket.accept();
        InputStreamReader inputStreamReader = new InputStreamReader(accept.getInputStream());

        char[] chars = new char[5];

        System.out.println("Client connected, waiting for input");

        while (true) {
            inputStreamReader.read(chars,0,chars.length);
            for (int i=0;i<5;i++) {
                if(chars[i]!='\u0000') {
                    System.out.print(chars[i]);
                }
            }
            inputStreamReader = new InputStreamReader(accept.getInputStream());
            chars = new char[5];
        }

    }
}

And when I send the characters "123456789" from the client, this is what I exactly see in the Servers terminal, but should not I be seeing only 12345 ?

Why the difference in the behaviour?
