Summary: 0004501: Specifying @Alternatives in beans.xml overrides do not work
Description: Specifying alternatives in beans.xml overrides do not work. For example, the following code will cause "hit()" instead of "mock-hit()" to be printed out:

================================================================================
package qa;

public interface Test {
  public void hit();
}
================================================================================

================================================================================
package qa;

public class TestBean implements Test {
  public void hit() {
    System.out.println("hit()");
  }
}
================================================================================

================================================================================
<beans xmlns="http://java.sun.com/xml/ns/javaee"> [^]
  <alternatives>
    <class>qa.MockTestBean</class>
  </alternatives>
</beans>
================================================================================

================================================================================
package qa;

import javax.enterprise.inject.Alternative;

@Alternative
public class MockTestBean implements Test {
  public void hit() {
    System.out.println("mock-hit()");
  }
}
================================================================================

================================================================================
package qa;

import javax.inject.Inject;

import org.junit.Test;
import org.junit.runner.RunWith;

import com.caucho.junit.ResinBeanConfiguration;
import com.caucho.junit.ResinBeanContainerRunner;

@RunWith(ResinBeanContainerRunner.class)
@ResinBeanConfiguration(beansXml = { "classpath:META-INF/beans.xml" })
public class JUnitTest {
  @Inject
  private qa.Test bean;

  @Test
  public void test() {
    bean.hit();
  }
}
================================================================================

This definitely appears to be a timing issue in that the underlying CDI context gets processed/bootstrapped before the beans.xml overrides are processed. For example, the following will work because no XML override is specified although the exact same META-INF/beans.xml will be loaded (via the default bootstrap as opposed to an override):

================================================================================
package qa;

import javax.inject.Inject;

import org.junit.Test;
import org.junit.runner.RunWith;

import com.caucho.junit.ResinBeanContainerRunner;

@RunWith(ResinBeanContainerRunner.class)
public class JUnitTest {
  @Inject
  private qa.Test bean;

  @Test
  public void test() {
    bean.hit();
  }
}
================================================================================

This is a pretty big problem since most developers are likely to use alternatives for mock objects in unit tests used through XML overrides rather than in production using the default beans.xml.
