> Since version 1.6.0.1 (including 1.6.0.2) (both webprofiles) in EL-expression on XHTML-pages one can no longer provide a 'subclass' as argument to a method with a method that takes a superclass as argument.
> In 1.6.0 webprofile this worked without problems 
> Consider 
> a class 
> @Named
> @RequestScoped
> public class Zoo {
>     private List<Animal> animals;
>     public Zoo() {
>         this.animals = new ArrayList<>();
>         this.animals.add(new Bird());
>         this.animals.add(new Mammal());
>     }
>     public List<Animal> getAnimals() {
>         return this.animals;
>     }
>     public String getName(Animal animal) {
>         return animal.getName();
>     }
> }
> and a hierarchy 
> Bird extends Animal
> Mammal extends Animal
> when iterating over the list of animals [Bird, Mamal] on an XHTML page
> calling zoo.getName(Bird) leads to an error stating
> SEVERE: Servlet.service() for servlet [FacesServlet] in context with path [/animaltest] threw exception [java.lang.NoSuchMethodException: org.animal.Zoo$$OwbNormalScopeProxy0.getName(org.animal.Bird)] with root cause
> java.lang.NoSuchMethodException: org.animal.Zoo$$OwbNormalScopeProxy0.getName(org.animal.Bird)
> 	at java.lang.Class.getMethod(Class.java:1624)
> 	at javax.el.BeanELResolver.invoke(BeanELResolver.java:394)
> 	at javax.el.CompositeELResolver.invoke(CompositeELResolver.java:225)
> 	at org.apache.el.parser.AstValue.getValue(AstValue.java:173)
> 	at org.apache.el.ValueExpressionImpl.getValue(ValueExpressionImpl.java:184)
> 	at org.apache.webbeans.el22.WrappedValueExpression.getValue(WrappedValueExpression.java:70)
> 	at org.apache.myfaces.view.facelets.el.ELText$ELTextVariable.writeText(ELText.java:219)
> However the EL expression should be aware of the method Zoo.getName(Animal) that perfectly allows any subclass of Animal as an argument.
> As this was working in 1.6.0 webprofile without problems I wonder what has changes if "only" security updates have been applied...
> Would be great if you can have a look at this.
> Thanks and best regards,
> Patrick
