I find that design of qualifier annotation poorly designed.   I understand the purpose of creating qualifier annotations but why all the complexity.   Why create custom annotations which takes a few lines?   It seems like overkill to me.

A much simpler design would be to create one single annotation with a text label parameter to identify branches or choices.  

For example an annotation named @Qualifier("text-label") would do the exact same thing without having to create custom user annotations and the complexity.

I would suggest that JBoss create the @Qualifier annotation and implement it in parallel with custom user annotation.
