The following code produces invalid bytecode:

<snip>
public class EnumBug {

    interface Interface {
        public int value();
    }
    
    public enum TheEnum implements Interface {
        ;
        
        TheEnum(int value) { this.value = value; }        
        public int value() { return value; }
        
        private int value;
    }
    
    public static void main(String[] args) {
        TheEnum x = null;
    }
}
</snip>

The same code compiles / executes fine with the Sun JDK compiler.
