The J2SE v1.4 API spec for ServerSocket.setReuseAddress(boolean on)
specification reads:
-----------------
public void setReuseAddress(boolean on)
                     throws SocketException

     Enable/disable SO_REUSEADDR. This option is set to true by default
when creating ServerSockets.
...
-----------------

However, in fact ReuseAddress is no longer true by default on Windows
since the b75. The following example demonstrates the problem:

---------------- Test.java -------------
import java.net.*;
import java.io.IOException;

public class Test {

    public static void main(String args[]) {
        try {
            ServerSocket soc = new ServerSocket();
            System.out.println("SO_REUSEADDR is " + soc.getReuseAddress()
+ " by default");
        } catch (IOException e) {
            e.printStackTrace(System.out);
        }
    }
}
---------------------------------------

Test output under Windows 2000:

# java -version
java version "1.4.0-beta_refresh"
Java(TM) 2 Runtime Environment, Standard Edition (build
1.4.0-beta_refresh-b75)
Java HotSpot(TM) Client VM (build 1.4.0-beta_refresh-b75, mixed mode)

# java Test
SO_REUSEADDR is false by default

Everything was working fine in b74 and before:

# java -version
java version "1.4.0-beta_refresh"
Java(TM) 2 Runtime Environment, Standard Edition (build
1.4.0-beta_refresh-b74)
Java HotSpot(TM) Client VM (build 1.4.0-beta_refresh-b74, mixed mode)

# java Test
SO_REUSEADDR is true by default

Please elimintate this inconsistency between the spec and implementation.
