> This problem was discovered when a test in jbossaop failed when using retro to run the tests in jdk1.4.
> The case:
> public class SuperPOJO<T extends java.util.AbstractList>
> {
>    private T fooObject;
>    public void setFoo(T arg) { fooObject = arg;}
>    public T getFoo() {return fooObject;}
> }
> public class SubPOJO extends SuperPOJO<java.util.ArrayList>
> {
>    private java.util.ArrayList bar;
>    public void setFoo(java.util.ArrayList a) { bar = a;}
>    public java.util.ArrayList getFoo(){ return bar;}
> }
> you can find the test under bridgemethods in jbossaop.
> SubPOJO will after compilation have a method like:
> public volatile AbstractList getFoo() { return getFoo() };
> - note that volatile is what the decompiler names it. more specifically
> its a bridge method created by the compiler.
> SubPOJO will have the method:
> public ArrayList getFoo() { return bar; }
> after jbossretro have changed java.util.AbstractList to
> edu.emory...AbstractList, the class will fail when its called.
