>       javaActivity.setArgDescriptors(objectDescriptor.getArgDescriptors());
>       objectDescriptor.setArgDescriptors(null);
>       javaActivity.setMethodName(objectDescriptor.getMethodName());
>       objectDescriptor.setMethodName(null);
>     }
> by setting the methodName to null in the object descriptor (objectDescriptor.setMethodName(null)), the object descriptor will not see it as a static factory method, but instead will look for the constructor of the class.
