FULL PRODUCT VERSION :
FOR JDK 1.4.0

Java version "1.4.0-beta3"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-beta3-b84)
Java HotSpot(TM) Client VM (build 1.4.0-beta3-b84, mixed mode)


FULL OPERATING SYSTEM VERSION :
  Windows 2000 Professional



EXTRA RELEVANT SYSTEM CONFIGURATION :
Apache webserver 1.3.22

Apache Tomcat 4.0.1

A DESCRIPTION OF THE PROBLEM :
When I first call java.net.URL.openStream() method for the
page containing no data, the method hangs for 15 seconds or
longer before returning -1. I verified that the stream is
closed prompty using telnet, but the call to the method
just hung for 15 seconds. The problem does not exist if
the page contains any charactor.

Here's the code snipet:

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

public class LongURL {
public static void main(String[] args) {
 try {
  URL emptyPageURL
    = new URL("http://localhost/emptypage.html");
  InputStream is= emptyPageURL.openStream();
System.out.println(System.currentTimeMillis());
  int c = is.read(); /* It takes 15 seconds to return -1 */
  System.out.println(System.currentTimeMillis());
  System.out.println("returned: "+c);
  } catch (Exception e) { e.printStackTrace(); }
}
}

As the name suggests, the emptypage.html is empty,
containing no charactor.


I tested the same code with JDK 1.3.1, and the same problem
exists. However when I tested with JDK 1.2.2, the call
returned -1 promptly. So the problem didn't exist for JDK
1.2.2.

REGRESSION. Last worked in version 1.2.2

EXPECTED VERSUS ACTUAL BEHAVIOR :
When new URL("http://localhost/emptypage.html").openStream
().read() is called, it should return -1 immediately.



This bug can be reproduced always.
