internal compiler error: can't find class$

Hi

I have just started to play with libgcj, and I am getting the following 
error when I am trying to compile some c++ code:

> internal compiler error: can't find class$

The c++ code I am compiling is a very simple piece of code, that 
includes to following line:

> coutUI * output_interface = new coutUI();

Here I am instantiating a new "coutUI" object; coutUI is a c++ class 
which is a sub-class of the java interface OutputInterface, implemented 
in the OutputInterface.java file:

> public interface OutputInterface {
>     public void addNode(BlueNode parent, BlueNode child);
>     public void checkQueue();
>     public void getText(String s);
> }

I compiled all the java source code (including OutputInterface.java) 
using gcj -C. Then I generated a corresponding .h file using gcjh, and 
it looks like this:

> #pragma interface
>
> #include <java/lang/Object.h>
>
> extern "Java"
> {
>   class OutputInterface;
>   class BlueNode;
> }
>
> class OutputInterface : public ::java::lang::Object
> {
> public:
>   virtual void addNode (::BlueNode *, ::BlueNode *) = 0;
>   virtual void checkQueue () = 0;
>   virtual void getText (::java::lang::String *) = 0;
>
>   static ::java::lang::Class class$;
> } __attribute__ ((java_interface));

I wonder where "static ::java::lang::Class class$;" comes from, since 
it seems to be the source of my problem...
Thank you for your help
