[cdi-dev] [JBoss JIRA] (CDI-627) fix wording regression for beans.xml alternative check introduced in 1.2

fix wording regression for beans.xml alternative check introduced in 1.2 ------------------------------------------------------------------------ Key: CDI-627 URL: https://issues.jboss.org/browse/CDI-627 Project: CDI Specification Issues Issue Type: Bug Components: Concepts Affects Versions: 1.2.Final Reporter: Mark Struberg Assignee: Mark Struberg Fix For: 2.0 .Final My scenario is the following: I have an @Alternative MockMailService class which should only be used during testing to not send out 5k mails to customers and employees when running the unit and integration test suite. {code} @Alternative @ApplicationScoped @Exclude(ifProjectStage=Production.class) public class MockMailService implements MailService {...} {code} Of course I only need to activate it in beans.xml: {code} <beans> <alternatives> <class>org.acme.MockMailService</class> </alternatives> </beans> {code} This is perfectly fine in CDI 1.0 but might be interpreted as not be allowed in the CDI 1.2 wording paragraph 5.1.1.2. "Declaring selected alternatives for a bean archive". Please note that we introduced a check in CDI 1.0 purely to help the customer eagerly detect possible wrong configuration. E.g. if he simply has a typo in the classname. It was _not_ intended to restrict useful use cases! What the intention was: all is fine IF one of * There exists a class T with the given name * That class T (or a contained producer field or producer method) is annotated with @Alternative * There is a Bean<T> with isAlternative() == true
