Our system is using the RedirectMatch in our Apache Web Server to redirect
cgi-bin command to other sites. This is working in well in 1.2.2_006 and
1.3.0-C but when tried in 1.3.0_02 and 1.2.2_007 the cgi-bin request stopped
working and gave the following error.

 java.lang.NullPointerException

The code to produce the results is as follows.

package nettest;
import javax.swing.*;
import javax.swing.filechooser.*;
import javax.swing.event.*;
import java.lang.*;
import java.io.*;
import java.net.*;
import java.awt.event.*;

public class Nettest extends JApplet {
    public Nettest() {
super();
    }

    public void init() {
super.init();
String url = JOptionPane.showInputDialog(getContentPane(),"Start test?");
System.out.println("url = " + url);

starttest("TRUSTEDHOST.hpl1.cb.lucent.com:8811/html/lucent/fm/dataservices/cgi-bin/DataSourceServices/dataSourceNameList?userId=bhavanas");
    }
    public void starttest(String url) {
String cbase = this.getCodeBase().toString();
String errStr = "";

     HttpURLConnection uc = null;
     try {
           URL whereto = new URL( cbase + url );
uc = (HttpURLConnection)whereto.openConnection();
InputStream in = uc.getInputStream();
} catch(NullPointerException n) {
n.printStackTrace();
} catch ( IOException ioe) {
try {
if(uc != null) {
errStr += uc.getResponseMessage();
} else {
errStr += ioe.toString();
}
System.out.println(errStr);
} catch ( IOException ex) {
errStr = "DataService Failure: ";
errStr += ioe.toString();
System.out.println(errStr);
}
}
    }
}

The problem is independent of browser or client platform.
