NetBeans only allows @Qualifiers to have:

@Target({ FIELD, PARAMETER })

or

@Target({ METHOD, FIELD, PARAMETER, TYPE })

This is too restrictive, because it fails to consider (e.g.) @Produces methods.

    @Produces
    @MyQualifier
    String getValue() {
        return "foo";
    }

This @Produces method might reasonably expect to satisfy a field and/or parameter injection point, but that would require that @MyQualifier be applicable to a METHOD as well. However, NetBeans rejects a qualifier that wants to use:

@Target({ METHOD, FIELD, PARAMETER })

It is therefore forced to include TYPE as well, despite @MyQualifier *not* being applicable to a type declaration.

Conversely, I also have previously also had reason to create qualifiers that have wanted to use only:

@Target(TYPE)

NetBeans doesn't like these either, although they are perfectly legal and accepted by WELD. Even worse, once NetBeans decides it doesn't like the @Target types on a qualifier, it refuses to use that qualifier for type-safe bean resolution.

I strongly suspect that this is what bug #225556 was trying to raise.
