Hi! Was not sure what mailing list to send this to but I guess some of you could help me out.
We are moving to JEE 7 and we are annotating our interceptors with @Priority(...) to not have to include them in all beans.xml in all archives where they should be used. The value for the @Priority annotation are based upon the constants defined in Interceptor.Priority... which JavaDoc says "Interceptors with smaller priority values are called first."... so far so good... Then I also want to be able to place alternatives in separate modules/jars that we will use in some test environments. This also works good using @Alternative and @Priority... I understand that the alternative is activated by using the @Priority annotation. In section 5.2.2 of the CDI 1.2 spec (e.g. http://docs.jboss.org/cdi/spec/1.2/cdi-spec-1.2.pdf) I read the following: "...all the beans left are alternatives with a priority, or producer methods or fields of beans that are alternatives with a priority, then the container will determine the highest priority value, and eliminate all beans, except for alternatives with the highest priority..." I have tested this and I'm fine with that the higher priority alternative is choosen. However in same spec in section 4.3 they have the following example: "@Alternative @Priority(APPLICATION+100) public class MockAsynchronousService extends AsynchronousService {" Similar example can be found at e.g.: https://docs.oracle.com/javaee/7/tutorial/cdi-adv002.htm To me its confusing to use a priority value based on Interceptors.Priority since the semantics of the Priority value is the opposite for interceptors and alternatives? Does the examples for alternatives only confuse me or did I miss someting?
