NullPointerException when compiling with akka

[chrisichris]

Hi,

when compiling the following code with the akka libs (http://akka,io) - I use the akka-actor-2.0.1.jar and scala-library.jar I get NullpointerException from the compiler.

The code is:

module org.yeb.akka;

import akka.actor:Actor, UntypedActor, ActorSystem, UntypedActorFactory;

import yeti.lang:Fun;

newActor system receiveFn = 

   (class YebUntypedActor extends UntypedActor

        void onReceive(Object msg)

            receiveFn this msg,

            

    end;   

   

    class YebUntypedActorFactory extends UntypedActorFactory

        UntypedActor create()

            new YebUntypedActor();

                

    end;

    (system is ~ActorSystem)#actorOf(new Props(new YebUntypedActorFactory())));

    

newActor;

And the exception:

 [java] java.lang.NullPointerException

The same excptions also happens when I put all the class code in a Java-File. Only referencing the akka classes seems to cause the NullPointerException

Seems that it was a bug in the asm 3.1 library used by Yeti compiler.
Hopefully patched with additional null-pointer check, try updated jar.
