GCJ problem with org.xml.sax package

["S. Park" <kanzuri@xxxxxxxxx>]

I'm experiencing some strange behavior with a simple class compiled with 
gcj 4.1 on FreeBSD 4.11 and 5.4 IA32. It compiles and runs as is, but if 
I subclass anything in the package org.xml.sax (e.g. by uncommenting the 
'extends' clause below), the executable seg faults. What's strange is 
that I can instantiate objects of types in that same package within the 
body of the main method. The problem only appears when subtyping. The 
test class looks like this:

import java.util.HashMap;
import org.xml.sax.helpers.DefaultHandler;
import org.xml.sax.InputSource;

public class Foo // extends DefaultHandler
{
       public static void main(String argv[])
       {
               InputSource is = new InputSource();
               String enc = is.getEncoding();

               DefaultHandler dh = new DefaultHandler();

               try
               {
                       dh.startDocument();
               }
               catch (Exception e)
               {
                       System.err.println(e.getMessage());
               }

               System.out.println(enc);

       }
}

Has anyone else run into this?
