When I tested this against the real server application, it turned out
not to work as I expected.
I got it working when I used something like this:

        UriBuilder builder = UriBuilder.fromUri( url ).path( path ).
                        resolveTemplate( "keyvalue", keyvalue );
        WebTarget target = client.target( builder );
        if (foo) {
            target = target.queryParam( "foo", Boolean.TRUE);
        }
        Response resp = target.request().headers( buildHeaders()).get();

In other words, the QueryParam wasn't (or at least didn't need to be)
valueless after all, it worked with a Boolean value.
This may be a bug in the documentation of the server application.

In this case, the parameter that looked valueless isn't a key value, but
a switch that controls what the server application does if it doesn't
find the data in its database.
