When making a socket connection to *certain* servers, BufferedReader.readLine() (or read() and read(char[], int, int] for that matter)
fails to recognize EOF.

One such server is Sun's FTP server (ftp.sun.com).  Observe the following code.

package MyUtils;

import java.io.*;
import java.net.*;

public class FTPTest
{
  public static void main(String[] args)
  {
    try {
      Socket sock = new Socket("ftp.sun.com", 21);
      sock.setSoTimeout(10000);
      BufferedReader reader = new BufferedReader(new
        InputStreamReader(sock.getInputStream()));

      String line = reader.readLine();
      System.out.println("line: [" + line + "]");
      while (line != null) {
        line = reader.readLine();
        System.out.println("line: [" + line + "]");
      }
    }
    catch (Exception e) {
      e.printStackTrace();
    }
    finally {
    }
  }
}
