Severe performance degradation of java webserver under JRE1.1.2

A severe performance degradation occurs in ServerSockets when running the 1.1.2 version of the JRE under Solaris 5.5 and 5.5.1, and using the ServerSocket.setSoTimeout(int) feature.

The following code snip will expose the problem:

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

class SST implements Runnable {

    static void p(String s) {
System.out.println(s);
    }

    public static void main(String[] a) throws Exception {

ServerSocket ss = new ServerSocket(3456);
ss.setSoTimeout(40000);
while (true) {
p("enter accept:");
Socket s = ss.accept();

p("accepted " +s);

Thread t = new Thread(new SST(s), "reader");
t.start();
}
    }

    SST(Socket s) {
this.s = s;
    }

    Socket s;

    public void run() {

try {
InputStream i = s.getInputStream();

int r;
while ((r = i.read()) > 0) {
System.out.write(r);
}
} catch (Exception e) {
e.printStackTrace();
}
    }
