Support type annotation in assignability of parameterized types --------------------------------------------------------------- Key: CDI-475 URL: https://issues.jboss.org/browse/CDI-475 Project: CDI Specification Issues Issue Type: Feature Request Components: Resolution Reporter: Antonin Stefanutti Since Java 8 provides support for type annotations, the assignability of parameterized types rules could be updated to support that feature that may add value in a number of use cases. For example, with lifecycle events resolution, instead of writing: {code} Set<Annotation> contextNames = new HashSet<>(); void camelContextNames(@Observes ProcessAnnotatedType<? extends CamelContext> pat) { if (pat.getAnnotatedType().isAnnotationPresent(ContextName.class)) contextNames.add(pat.getAnnotatedType().getAnnotation(ContextName.class)); } {code} One could directly write: {code} void camelContextNames(@Observes ProcessAnnotatedType<@ContextName ? extends CamelContext> pat) { contextNames.add(pat.getAnnotatedType().getAnnotation(ContextName.class)); } {code}
