NullPointer when try to read property

[all]

Using play-1.0.1

When I try to read a property of an object I've got a NullPointerException.

The object is not part of my model.

Just try this code in a new play application. :

---------------------------------------------------------------------

import java.awt.Point;

public class Application extends Controller {

    public static void index() {
     Point p = new Point();
     p.x=5;
     System.out.println(p.x);
        render();
    }

}

-------------------------------------------------------------------

It fires an exception :

play.exceptions.JavaExecutionException
        at play.mvc.ActionInvoker.invoke(ActionInvoker.java:229)
        at Invocation.HTTP Request(Play!)
Caused by: java.lang.NullPointerException
        at play.classloading.enhancers.PropertiesEnhancer$FieldAccessor.invokeReadProperty(PropertiesEnhancer.java:171)
        at controllers.Application.index(Application.java:14)
        at play.utils.Java.invokeStatic(Java.java:129)
        at play.mvc.ActionInvoker.invoke(ActionInvoker.java:138)
        ... 1 more

--------------------------------------------------------------

Did I miss something ?

Ah yes. I've already fixed that in the trunk. Please check with the
latest 1.0 nightly
