[jira] [Created] (TOMEE-1205) TomEE webprofile 1.6.0.1 and 1.6.0.2
breaks java subtyping
Patrick Pekczynski created TOMEE-1205:
-----------------------------------------
Summary: TomEE webprofile 1.6.0.1 and 1.6.0.2 breaks java subtyping
Key: TOMEE-1205
URL: https://issues.apache.org/jira/browse/TOMEE-1205
Project: TomEE
Issue Type: Bug
Affects Versions: 1.6.0.1, 1.6.0.2
Environment: Windows 7 64 Bit
java version "1.7.0_21"
Java(TM) SE Runtime Environment (build 1.7.0_21-b11)
Java HotSpot(TM) 64-Bit Server VM (build 23.21-b01, mixed mode)
1.6.0.1 webprofile
1.6.0.2 webprofile
Reporter: Patrick Pekczynski
Priority: Blocker
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
