Pete Muir commented on CDI-234:
-------------------------------

This was discussed at yesterdays EG meeting

{quote}
  - Definitely do this, removes a wart
  - Concern that JDK defined equality of arrays is not ideal in many cases for the way people use arrays on qualifiers
  - discussed a declarative approach (e.g. @Unordered)
  - discussed a SPI approach (user can specify a comparator to use)
  - discussed that we should expose a BeanManager.compare(qualifier1, qualifier2) type method that applys rules (https://issues.jboss.org/browse/CDI-223)
  - group preferred SPI approach

> The spec says:
> "Array-valued or annotation-valued members of a qualifier type should be annotated @Nonbinding in a portable application.
> If an array-valued or annotation-valued member of a qualifier type is not annotated @Nonbinding, non-portable behavior
> results."
> The case of arrays without this annotation should be managed to get a better portability. The equality of arrays is determined through "Arrays" helper (http://docs.oracle.com/javase/1.5.0/docs/api/java/lang/annotation/Annotation.html) so i don't think there is any technical issue to consider arrays as a field.
