Can't inject generic type by HK2 to CDI

Let's say I have

```
@Contract
public class MyContract

@Service
public class MyService implements MyContract
```

I'm trying to make this injectable by HK2 into CDI using Hk2CustomBoundTypesProvider.

The CDI bean has

```
@Inject
MyContract beanByHk2;
```

In the custom bound types provider, if I do something like

```
@Override
public Set getHk2Types() {
Set set = new HashSet<>();
set.add(MyContract.class);
return set;
}
```

I get

> org.jboss.weld.exceptions.DeploymentException: WELD-001408: Unsatisfied dependencies for type MyContract with qualifiers @Default

This is probably fine. But if I do something like

```
@Override
public Set getHk2Types() {
Set set = new HashSet<>();
set.add(new ParameterizedTypeImpl(MyContract.class, String.class));
return set;
}
```

I get

I think this is the bug here. The getHk2Types returns Set, but the returned members seem to be cast to Class, failing to accept any other Type implementations.
