Strange NullPointerException

Hello. I've been away for some time, but now I'm Back :P

I'm getting a really wierd problem on generated proxy class. The 
generated code is as follows (except for System.out.println that I have 
added for some debug):

   public void run() {
       System.out.println("Tou no run do proxy !!!!!!!!!");
      try {
         System.out.println("O link e " + link);
         System.out.println("O this e : " + this);
         Object target = link.fetch (this, Lock.LEVEL_WRITE);
         System.out.println("O target e " + target);
         if (target!=null) {
            ((kernel.ExecutionElement) target).run();
         } else {
            Object[] args   = {};
            Object   result = link.invoke(this, 12, args, Lock.LEVEL_WRITE);
         }
      } catch (ExceptionInOzoneObjectException e) {
         Throwable ee = e.getCause();
        
         // Hope that the compiler is not so smart and detect these 
statements as unreachable if these exceptions are already matched above
         if (ee instanceof RuntimeException) {
             throw (RuntimeException) ee;
         }
        
         if (ee instanceof Error) {
             throw (Error) ee;
         }
        
         throw e; // Unhandled exception.
      } catch (RuntimeException e) {
         e.fillInStackTrace();
         throw e;
      } catch (Exception e) {
         e.fillInStackTrace();
         throw new UnexpectedException (e.toString());
      }
   }

On the STDOUT I'm getting the following:
     [java] Tou no run do proxy !!!!!!!!!
     [java] O link e org.ozoneDB.Database@13e0aba
     [java] O this e : class kernel.ExecutionElement_Proxy remoteID:113
     [java] java.lang.NullPointerException
     [java]     at kernel.ExecutionElement_Proxy.run(Unknown Source)
     [java]     at 
EDU.oswego.cs.dl.util.concurrent.PooledExecutor$Worker.run(Po
oledExecutor.java:725)
     [java]     at java.lang.Thread.run(Thread.java:534)


I'm running this via a PooledExecutor, thats because the stack trace 
reports it. However, because of the System.out.println one can state 
that the problem is in the link.fetch method. The "this" object is, as 
printed, kernel.ExecutionElement_Proxy remoteID:113.

What am I doing wrong ?

Please be as fast as you can, I'm going mad.

Thank you very much,
Goncalo.
