[dhanaraj]

Its is reproducible in the latest version of dozer-5.5.1.jar

[dhanaraj]

public interface SomeInterface {
public void setChildren(List <? extends SomeInterface>);
public List <? extends SomeInterface> getChildren();
}

public class SomeType implements SomeInterface {
private List children;
public setChildren(List <? extends SomeInterface>
...
}
}

When this "SomeType" is mapped by dozer it fails with java.lang.ClassCastException: sun.reflect.generics.reflectiveObjects.WildcardTypeImpl cannot be cast to java.lang.Class

@dhanaraj ; is this still an issue? if so, can you create a github repo, that includes a unit test showing this behaviour and link it here.
