If one is using qualifiers that make use of binding members, a resolution error message like the following fails to adequately describe which qualifiers are involved:

Caused by: org.jboss.weld.exceptions.AmbiguousResolutionException: WELD-001318: Cannot resolve an ambiguous dependency between:

• Producer Method [Optional] with qualifiers [@Claim @Claim @Claim] declared as [[UnbackedAnnotatedMethod] @Claim @Dependent @Produces org.eclipse.microprofile.jwt.wfswarm.cdi.CustomClaimProducer.genericOptionalClaimProducer(InjectionPoint)],
• Producer Method [Object] with qualifiers [@Claim @Claim @Claim] declared as [[UnbackedAnnotatedMethod] @Claim @Dependent @Produces org.eclipse.microprofile.jwt.wfswarm.cdi.CustomClaimProducer.genericClaimProducer(InjectionPoint)]

where Claim is:

@Qualifier

@Retention(RetentionPolicy.RUNTIME)

@Target({ElementType.FIELD, ElementType.METHOD, ElementType.PARAMETER})

public @interface Claim {

    /**

     * The value specifies the id name the claim to inject

     * @return the claim name

     * @see JsonWebToken#getClaim(String)

     */

    String value() default "";

    /**

     * An alternate way of specifying a claim name using the {@linkplain Claims}

     * enum

     * @return the claim enum

     */

    Claims standard() default Claims.UNKNOWN;

}

In general, it would be good if the messages involving qualifiers that have binding members would print out the binding members to help with identifying the context that is involved.
