[jboss-jira] [JBoss JIRA] (WFLY-3456) Can not call method with generic type parameter with null value

[Tamas Bodis (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-3456?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13089562#comment-13089562 ] 

Tamas Bodis commented on WFLY-3456:
-----------------------------------

With this modification (in WildFly 9.0.0.Final) we cannot access now the 'bridge' methods. 
This makes sense for the first time, but now if we try to call a package private class's public method through a public subclass, than we cannot reach it (MethodNotFoundException) because _from outside_ we see that method as a bridge method. Like in this example:

{code:title=Parent.java|borderStyle=solid}
class Parent {
    public String methodToCall() {
        return "value";
    }
}
{code}

{code:title=Child.java|borderStyle=solid}
public class Child extends Parent {
}
{code}

{code:title=test.jsp|borderStyle=solid}
  ${child.methodToCall()}
{code}

And because there are frameworks (like Spring Data in our case) which use this kind of API encapsulation we cannot switch to WildFly9 easily. Do you have any idea how to solve this problem in general in the future releases?
