JSON-B transient and property annotation collide unexpectedly

Originally raised by @sdaschner in these issues:

Describe the bug
When mapping a class via JSON-B, and annotating fields as follows, the result throws an error because of mismatching types:

public class Coffee {

    @JsonbTransient
    private Order order;

    @JsonbProperty("order")
    private URI orderLink;

    Coffee() {
        order = new Order();
        orderLink = URI.create("http://localhost/");
    }

    // getters & setters
}

this results in:

[ERROR   ] Unable to serialize property 'order' from com.sebastian_daschner.openliberty.Coffee
[ERROR   ] Generating incomplete JSON
[ERROR   ] Problem with writing the data, class com.sebastian_daschner.openliberty.Coffee, ContentType: application/json

If both properties order and orderLink have the same type, it works as expected (i.e. orderLink is serialized as "order").

However, if we annotate @JsonbProperty on the setter instead, it works:

public class Coffee {

    @JsonbTransient
    private Order order;

    private URI orderLink;

    // [...]

    @JsonbProperty("order")
    public URI getOrderLink() {
        return orderLink;
    }

}

Response:

{"order":"http://localhost/"}

There seems to be an unexpected type link of the (ignored) property with the default serialized JSON key "order", and the custom name binding.

To Reproduce
See code snippets in description

Expected behavior
Original code should deserialize into the expected JSON of:

{"order":"http://localhost/"}

instead of throwing an error

@aguibert I can try to fix this.

@aguibert the problem is not happening in current version. It may have already been fixed.
