Resolution: Fixed

> Key: ARIES-2059
> URL: https://issues.apache.org/jira/browse/ARIES-2059
> Project: Aries
> Issue Type: Bug
> Components: CDI
> Reporter: Raymond Augé
> Assignee: Raymond Augé
> Priority: Major
> Fix For: cdi-1.1.4
>
>
> Component properties are sometimes merged in the incorrect order.
> This was caused by the following misuse of the CDI annotated APIs as follows:
> When a repeatable annotation is defined on a class, the API
> {{javax.enterprise.inject.spi.Annotated}} can be misleading because {{<T
> extends Annotation> Set<T> getAnnotations(Class<T> annotationType);}} returns
> a Set.
> This means that implementations are free to return annotations not in
> definition order.
> Aries CDI mistakenly used this API to retrieve {{@PID}} annotations (which
> are repeatable.)
> The work around is pretty simple, when needing to retrieve repeatable
> annotations in definition order pass the container annotationType (all
> repeatable annotations have a container annotation type) to the method
> instead, in this case {{getAnnotations(PIDs.class)}} and then get the
> {{@PIDs.value()}} array which contains the {{@PID}} annotations in definition
> order.
> Note that when there is only a single instance of a repeatable annotation,
> only an instance of the repeatable annotation is used in the class and NOT an
> instance of the container with an array of length 1. This means that you need
> to check first for the container, and then for single instances in order to
> catch all usage scenarios.
