Just to improve the question. The right link is https://github.com/caelum/vraptor4/issues/897

We have this interface:

public interface CacheStore<K,V> {

    V write(K key, V value);

    [...]

}

And this implementation:

public class DefaultCacheStore<K,V> implements CacheStore<K,V> {

    [...]

}

This works fine using Weld 2.1.x. But when we migrate to Weld 2.2.x, we got this error:

Caused by: org.jboss.weld.exceptions.DeploymentException:

WELD-001408 :
