FreeBSD/i386 problem

[NAKATA Maho]

Dear lists,
I'm interested in using gcj with FreeBSD 5.4-RELEASE but
unfortunately, this small test program fails,
with gcc-4.1-20050716, configured like:
% /work/gcc41/bin/gcj -v
Using built-in specs.
Reading specs from /work/gcc41/lib/gcc/i386-unknown-freebsd5.4/4.1.0/../../../libgcj.spec
rename spec lib to liborig
Target: i386-unknown-freebsd5.4
Configured with: ../configure --enable-java-awt=xlib,gtk --prefix=/work/gcc41
Thread model: posix
gcc version 4.1.0 20050716 (experimental)

% cat ClassLoaderTest.java
import java.net.*;

public class ClassLoaderTest {
    public static void main(String[] args) throws Exception {
        URL[] bootPath = new URL[1];
        bootPath[0] = new URL("file:/usr/X11R6/lib/mozilla/chrome/JP.jar");
                URLClassLoader loader = new StartupClassLoader(bootPath, null);
                Class clazz = loader.loadClass("Test");
    }
}

class StartupClassLoader extends URLClassLoader {
    public StartupClassLoader(URL[] urls, ClassLoader parent) {
        super(urls, parent);
    }
}

% setenv LD_LIBRARY_PATH /work/gcc41/lib
% /work/gcc41/bin/gcj -o foo --main=ClassLoaderTest ClassLoaderTest.java
% ./foo
Abort (core dumped)

Using GNU/Linux, correct out put might be:

% ./foo
Exception in thread "main" java.lang.ClassNotFoundException: Test not found in StartupClassLoader{urls=[file:/usr/X11R6/lib/mozilla/chrome/JP.jar], parent=null}   at java.net.URLClassLoader.findClass (URLClassLoader.java:1011)
   at java.lang.ClassLoader.loadClass (ClassLoader.java:317)
   at java.lang.ClassLoader.loadClass (ClassLoader.java:260)
   at ClassLoaderTest.main (foo)
 
so exception is not correctly thrown for FreeBSD. 
Any hints are extremely appreciated!
