[jnc-users] NullPointerException in HTTPUrlConnection

[A. 's. A. <str...@gm...>]

Hi, I just had the same problem Avi Cohen reported a couple months ago.
Using a url that does not exist leads to a NPE. The code I used for testing
is almost the same:

import java.net.URL;
import java.net.URLConnection;

public class URLConnectionTest {
    static public void main(String[] args) {
        try {
            URL u = new URL("http://www.hasdklashdklj.com/");
            System.out.println(u);
            URLConnection c = u.openConnection();
            System.out.println(c);
            c.connect();
            System.out.println("done");
        } catch (Exception e) {
            System.out.println("nono");
            e.printStackTrace();
        }
    }
}

Here's the setup:

JNC-1.1.1
gcc-122233
Using Windows XP
Compiling for Windows
Compiling from source
Config:
Not excluding JCE
Not optimizing
Not stripping
Not packing
All the other options are the default  (new project)

Here's the output:

A. exclude JCE, add GNU regex

http://www.hasdklashdklj.com/
nono
java.lang.NullPointerException
   at
java.net.URLConnection.toString(/usr/local/src/gcc/libjava/classpath/java/net/URLConnection.java:627)
   at
java.io.PrintStream.println(/usr/local/src/gcc/libjava/java/io/PrintStream.java:473)
   at URLConnectionTest.main(C:/DOCUME~1/andre/CONFIG~1/Temp/ccOsbaaa.jar:0)


B. not excluding JCE, not adding GNU regex (does not seem to interfer, tried
with and without)

http://www.hasdklashdklj.com/
gnu.java.net.protocol.http.HTTPURLConnection:http://www.hasdklashdklj.com/
nono
java.lang.NullPointerException
   <<No stacktrace available>>


The output in eclipse is

http://www.hasdklashdklj.com/
sun.net.www.protocol.http.HttpURLConnection:http://www.hasdklashdklj.com/
nono
java.net.UnknownHostException: www.hasdklashdklj.com
    at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:177)
(...)


Anybody has a workaround? I can't find a way to check the URL without using
URL.openConnection().
