ClassCastException with generic method

by Guillaume Jeudy :: Rate this Message:

Hi,

I'm trying to test a generic method. Is that possible with jmock2? I tried one(jaxbUnmarshaller).unmarshal(with(any(Class.class), with(any(String.class))) but that also fails.

expectations code:

this.mockContext.checking(new Expectations() {{
one(jaxbUnmarshaller).unmarshal(with(Issue.class), with(any(String.class)));
}});

interface:

public interface JAXBUnmarshaller {

<T> T unmarshal(Class<T> expectedType, InputStream inputStream) throws JAXBException;
}

throws:

java.lang.ClassCastException: java.lang.Object
