@Specializes not resolving @Named

When i have the situation above:

@Alternative
@Stereotype
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.TYPE)
public @interface ETC {}

public abstract class BpmExpressionService {
public final static String NAME = "bpmExpressionService";
}

@Stateless
@Named(BpmExpressionService.NAME)
public class EppBpmExpressionService extends BpmExpressionService {}

@ETC
@Stateless
@Named(BpmExpressionService.NAME)
public class EtcBpmExpressionService extends EppBpmExpressionService {}

@Stateless
@Specializes
public class EtcmpaBpmExpressionService extends EtcBpmExpressionService {}

beans.xml file:

<beans xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/beans_1_0.xsd">

<alternatives>
<stereotype>

.ETC</stereotype>
</alternatives>
</beans>

Following validation error occurs:

Caused by: org.jboss.weld.exceptions.DeploymentException: WELD-001414 Bean name is ambiguous. Name bpmExpressionService resolves to beans [Session bean [class br.com.infox.bpm.cdi.qualifier.EtcmpaBpmExpressionService with qualifiers [@Default @Any @Named]; local interfaces are [EtcmpaBpmExpressionService], Session bean [class br.com.infox.ibpm.event.EppBpmExpressionService with qualifiers [@Default @Any @Named]; local interfaces are [EppBpmExpressionService]]

But CDI specification says :

"When an enabled bean specializes another bean, the other bean is never instantiated or called by the container. Even if the other bean defines a producer or observer method, the method will never be called."

"Furthermore, if the default implementation declares a bean EL name using @Named, the name is inherited by the specializing alternative bean."

I changed JBossEAP weld version from 1.1.17 (redhat) to 1.1.33 and the error persist.

What a could analyze the container is not undestanding EppBpmExpressionService is specialized by EtcmpaBpmExpressionService.
