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

behavior of arrays without @Nonbinding
--------------------------------------
Key: CDI-234
URL: https://issues.jboss.org/browse/CDI-234
Project: CDI Specification Issues
Issue Type: Feature Request
Components: Concepts
Affects Versions: 1.0
Reporter: Romain Manni-Bucau
Assignee: Pete Muir
Priority: Minor
Fix For: 1.1.PRD
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/Annotat...) so i
don't think there is any technical issue to consider arrays as a field.
