CDI tools core doesn't take into account disabled beans while resolving beans.

5.1.2. Enabled and disabled beans
A bean is said to be enabled if:
• it is deployed in a bean archive, and
• it is not a producer method or field of a disabled bean, and
• it is not specialized by any other enabled bean, as defined in Section 4.3, "Specialization", and either
• it is not an alternative, or it is a selected alternative of at least one bean archive.

org.jboss.tools.cdi.core.test.tck.ResolutionByNameTest.testAmbiguousELNamesResolved() should pass.
