And now for some non-tape or 700/92 terminal questions (friday hp3000-l
discussions)...

Now I have Java running, I want to use it.  I think that sounds
resonable. :)

I have typed in a chat client/server program that I got from the day
long seminar at HPWorld.  The presenter was not a 3000 type, but Java
should be Java right?

The program is failing with a SIGBUS error when it tries to open a
listener on a server socket:
-----------------------------------------------
shell/iX> java ChatTest
No Floating-Point coprocessor, disabling JIT
Enter main
SIGBUS    10*  bus error
Sig = 10; code = 18.

Full thread dump:
[skip dump since it is rather large]
-----------------------------------------------
I stripped the program down just to get the bare minimum and here it
is...

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

public class ChatTest {

 public static void main( String arg[]) {
     try {
System.out.println("Enter main");
ServerSocket s = new ServerSocket (1234);
System.out.println("After get socket: ");
System.out.flush();
         }
     catch(IOException e) { System.out.println("Exception: "+ e); }
 }
}

----------------------

Do I need to set anything up from a networking standpoint?  I have used
different port numbers, but if that was the failure, I would expect the
IOException to be thrown.

It isn't security/permissions since I can be an SM and get the same
message.

Any ideas?
