Must a qualifier be meta-annotated with javax.inject.Qualifier?

ljnelson Feb 2, 2018 3:21 PM

The specification says:

A qualifier type is a Java annotation defined as @Retention(RUNTIME). Typically a qualifier type is defined as @Target({METHOD, FIELD, PARAMETER, TYPE}).
A qualifier type may be declared by specifying the @javax.inject.Qualifier meta-annotation.

BeanAttributes#getQualifiers() returns only annotations that have, themselves, been annotated with javax.inject.Qualifier. Is this correct? (Note the usages of "is" and "may be" above.)

Hi Laird,
I think that BeanAttributes#getQualifiers() also returns the annotations enhanced by javax.enterprise.inject.spi.BeforeBeanDiscovery.addQualifier(Class<? extends Annotation>). In other words, "A qualifier type may be declared..." does not forbid other ways of declaration.
