OgnlValueStackTest issues

Downloaded Struts 2.3.4 last week and ran into alot of issues with com.opensymphony.xwork2.ognl.OgnlValueStackTest setValue /Ognl findValue
Background:: accessing objects the 'Ognl hierarchy' I always found what i was looking for e.g.
Foo foo=new Foo();
Dog dog = new Dog();
foo.setDog(dog);
vs.setValue("foo", foo);
Object o=vs.findValue("Foo.Dog") //returns dog object embedded in foo
if(o instanceof Dog) //always true no problem here
{
Dog dog=(Dog)o; //Cast is correct without errors or exceptions
}
but failure when using OGNL to access orphaned objects e.g.
public void testDoesNotFailOnNonActionObjects()

{ //if a value is not found, then it will check for missing properties //it needs to check in all objects in the stack, not only actions, see //WW-3306 OgnlValueStack vs = createValueStack(); Dog dog = new Dog(); dog.setHates(null); vs.push(dog); //dog is set into vs Object o =vs.findValue("hates"); //o returns null }

Has anyone been able to run OgnlValueStackTest w/o failures and errors recently?
Thanks,
