Viacheslav Kabanovich commented on JBIDE-15385:
-----------------------------------------------

Test case.

Create CDI 1.1 project.
Create classes 

{code}
package test;

import javax.enterprise.context.ApplicationScoped;

@ApplicationScoped
public class A {

}
{code}

{code}
package test;

import javax.annotation.Priority;
import javax.enterprise.context.ApplicationScoped;
import javax.enterprise.inject.Alternative;

import static javax.interceptor.Interceptor.Priority.APPLICATION;

@ApplicationScoped
@Alternative
@Priority(APPLICATION + 200)
public class B extends A {

}
{code}

{code}
package test;

import javax.annotation.Priority;
import javax.enterprise.context.ApplicationScoped;
import javax.enterprise.inject.Alternative;

import static javax.interceptor.Interceptor.Priority.APPLICATION;

@ApplicationScoped
@Alternative
@Priority(APPLICATION + 300)
public class C extends A {

}
{code}

{code}
package test;

import javax.enterprise.context.ApplicationScoped;
import javax.inject.Inject;

@ApplicationScoped
public class Test {
	@Inject A a; 
}
{code}

Check that injection Test.a is resolved to bean test.C.

In bean test.B change value in @Priority from 200 to 300.
Check that a warning 'Multiple beans...' appeared at injection Test.a.

In bean test.B change value in @Priority 400.
Check that the warning is disappeared and injection Test.a is resolved to bean test.B.

Add to test.B annotation @Vetoed (javax.enterprise.inject.Vetoed).
Check that injection Test.a is resolved to bean test.C.

> That makes it enabled without declaring it in beans.xml.
> Value of Priority is used to resolve ambiguous dependencies.
