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

             Summary: PropertyNotFoundException when the property is a defender method
                 Key: WFLY-3687
                 URL: https://issues.jboss.org/browse/WFLY-3687
             Project: WildFly
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: 8.1.0.Final
            Reporter: Rich DiCroce
            Assignee: Jason Greene


I have a class that implements an interface that uses Java 8's new defender methods feature. Some getters on the interface have default implementations, and the concrete classes don't override them.

If I try to refer to one of these getters as a property like so:
{code:xml}
value="#{cc.filter.filter.valueChoices}"
{code}

Then I get this exception:

Caused by: javax.el.PropertyNotFoundException: The class 'com.lapis.jsf.framework.dao.search.DefaultEntityFilter' does not have the property 'valueChoices'.

Two workarounds exist. One: you can override the default method in a concrete class and have it just call the default super method. Two: you can call the getter using a method expression instead of a value expression.
