Clarify "contains" meaning in "Legal bean types" specification.

Details

    Description

      CDI 1.1, section 2.2.1. Legal bean types says:

      A parameterized type that contains a wildcard type parameter is not a legal bean type.

      Does it means direct containment or deep/recursive containment?

      I understand this is clearly illegal:

      @Produces
List<?> produceList(){
//...
}

      But, are those two bean definitions legal:

      @Produces
List<Optional<?>> produceList(){
//...
}

      // Bean types: MyList, List<Optional<?>>, Object
// or
// Bean types: MyList, Object
@Dependent
MyList extends List<Optional<?>> {
//...
}

          relates to

          Bug - A problem that impairs or prevents the functions of the product. WELD-1492 Producers with parameterized return types with a nested parameterized type containing a wildcard or type variable are not detected as invalid

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
