Cannot register Converter for XStream unless I also own the target class.

[rankinc]

Hi,

I have a DataTable that I am trying to convert into List<Target>. I've written a suitable TargetConverter for Target, but have discovered that Cucumber won't invoke my Converter unless I also annotate Target with @XStreamConverter. Unfortunately, the Target class is not mine to annotate. Subclassing Target does work, but is fugly.

Is there any other way to associate my Target class with TargetConverter please? If not, perhaps Cucumber could provide a mechanism to do so, e.g. some kind of top-level annotation on the step definition class?

@CustomerConverters({
    @CustomerConverter(value = TargetConverter.class, type = Target.class, priority = 1),
    ...
})
public class MySteps {

    @Given("^we have stuff like:")
    public void setStuff(List<Target> stuff) {
        ...;
    }

}

Or maybe even:

@XStreamConverters(
    @XStreamConverter(TargetConverter.class)
)
@RunWith(Cucumber.class)
public class RunCukesTest {
}

which would probably be clearer. The converters could then be registered with the LocalizedXStreams object up front by passing them to Runtime via RuntimeOptions. Does this sound reasonable, please?
