The same problem might apply to org.jboss.cdi.tck.tests.extensions.lifecycle.processBeanAttributes.VerifyValuesTest.

There is a class

@Alternative

public class Mike {}

and the test checks that there is no ProcessBeanAttributes fired for this class (because it's a not-enabled alternative).
But what happens if I would like to return false in BeanAttributes#isAlternative().
Whether that bean ends up enabled or not can imo only be judged after ProcessBeanAttributes.
