RMI server fails at constructor

["Rui Wang" <Rui dot Wang at newcastle dot ac dot uk>]

Hello, 

I knew this is probably not a new question to the achieves. However,
having read the related posts, I have no luck of finding the right
answer. I am new to GCJ, and trying to compile an very basic RMI server
to native code on WinXP. Any help would be appreciated!! 

The GCJ I am using is ThisisCool GCJ 4.0.2 version. My
server("GRMIServerImpl")is quite minimal, and I have pasted its code at
the button of this email. 

Here is my build batch file: 

setlocal
set prompt=?

PATH %cd%\bin;%PATH%
set MAIN=GRMIServerImpl

mkdir bin
mkdir obj

gcj -C -fCLASSPATH=bin -d bin src\GRMIServer.java
gcj -C -fCLASSPATH=bin -d bin src\GRMIServerImpl.java

pushd .\bin
grmic -vcompat GRMIServerImpl
copy GRMIServerImpl_Stub.class ..\..\client\src
popd

gcj --classpath=bin -c bin\GRMIServer.class -o obj\GRMIServer.o
gcj --classpath=bin -c bin\GRMIServerImpl.class -o obj\GRMIServerImpl.o
gcj --classpath=bin -c bin\GRMIServerImpl_Skel.class -o
obj\GRMIServerImpl_Skel.o
gcj --classpath=bin -c bin\GRMIServerImpl_Stub.class -o
obj\GRMIServerImpl_Stub.o
copy src\policy.all obj\

gcj obj\*.o --main=%MAIN% -o %MAIN%.exe
-Djava.security.policy=policy.all

Endlocal

After the build, if I run GRMIServerImpl.exe, it's going to throw a
error message:
D:\GCJTest\RMI\RMISimpleExample\server>GRMIServerImpl.exe
1
Exception in thread "main" java.lang.ExceptionInInitializerError

Anyone know what cause this exception? My RMI server source code is the
following:
import java.rmi.*;
import java.rmi.server.*;
import java.rmi.registry.*;

public class GRMIServerImpl extends UnicastRemoteObject
                             implements GRMIServer
{

	GRMIServerImpl() throws RemoteException
	{
		super();
	}

	// remote method
	public int sum(int a,int b) throws RemoteException
	{
		return a + b;
	}

	public static void main(String args[])
	{
		//set the security manager
		try
		{
			System.setSecurityManager(new
RMISecurityManager());
			System.out.println("1");

			//create a local instance of the object
			GRMIServerImpl server = new GRMIServerImpl();
			//put the local instance in the registry
			String url = "rmi://localhost:1099/GRMISevice";
			
			System.out.println("Binding server to " + url +
"...");
			Naming.rebind(url, server);
			System.out.println("Server waiting.....");
		}
		catch (java.net.MalformedURLException me)
		{
			System.out.println("Malformed URL: " +
me.toString());
			me.printStackTrace();
		}

		catch (RemoteException re)
		{
			System.out.println("Remote exception: " +
re.toString());
			re.printStackTrace();
		}
		catch(Exception ex)
		{
			System.out.println("Exception: " +
ex.toString());
			ex.printStackTrace();
		}

	}
}

Best Regards
