I know we discussed this back in May of 2016, but actual practice is causing us to scratch our heads... Without the @Repeatable annotation usage being spelled out at the Platform level, we're discovering some inconsistent or incomplete usage patterns.
For example, JPA has stepped up to use the @Repeatable annotation on several of their annotations. And, Common Annotations has identified the use with @Resource and @DataSourceDefinition. But, what about @EJB? It seems that this would be another valid usage of @Repeatable. So, with each spec deciding for themselves whether to support @Repeatable, we don't have a consistent story for our users. It won't be intuitive. Sometimes you can skip the plural form of the annotation, and sometimes you can't. You'll just have to "know"...
I haven't thought through every plural Annotation usage, so I'm not sure if the @EJB is the only miss. If we're down to just a handful of misses, should we step up to support these additional @Repeatables in Java EE 8?
