Wildcard Generic Fields class cast exception

[Ryan Bergman]

Hello, I have some beans that are generated by JAX-B. I want to populate them all with some junk for some tests. So far I love the PODAM library but I am running into one snag I'm not sure how to get around. Some beans have some windcard types like this:

    @XmlElementRef(name = "reportedLocation", namespace = "http://api.foo.com/v3", type = JAXBElement.class)

    protected List<JAXBElement<? extends ReportedLocation>> reportedLocations;

When PODAM hits this I get this exception:

java.lang.ClassCastException: sun.reflect.generics.reflectiveObjects.WildcardTypeImpl cannot be cast to java.lang.Class

Any idea on this? again, this is a property of another object up the object graph so it's not obvious how to register something to get around it.

 Also It might be nice to have a brute force option so you could tell PODAM that if it hits a snag on one property to just keep going and do whatever else it can.

Thanks for a great library!

This is a clear bug in Podam resolving a type of variable.. I don't think it's good idea to suppress it as it forces people to report issues ;)
I've reported your issue to GitHub https://github.com/devopsfolks/podam/issues/216

Thanks, Daniil
