Is it possible to suppress bean injection?

Question

I have an web app which is to be deployed on Wildfly 12. Included in the app is a third party jar with code similar to the following

class X
{
    @Inject private Y y = null;

    public void someMethod()
    {
        if (y == null)
            doSomething();
        else
            doSomethingElse(y);
    }
}

It's clear that the code has been written under the assumption that injection may fail and y can be null.

However Weld doesn't like this and I get a deployment error saying there is a unsatisfied deplendency for y. I can't modify the third party code and I don't want to supply a dependency for y. I would like the doSomething() branch to be taken.

Is it possible to tell Weld not to try and inject anything at this injection point?

Thanks.

Might be overkill, but you can create a producer that always returns null for that class:

@ApplicationScoped
public class YProducer {

    @Produces
    @RequestScoped  
    public Y create() {
        return null;
    }

    public void destroy(@Disposes Y y) {
        //no-op
    }
}
