AnnotationUtils fails to throw exception if meta-annotation is not present [SPR-13335]

[spring-projects-issues]

Sam Brannen opened SPR-13335 and commented

Status Quo

It is a user configuration error if an alias is configured via @AliasFor for an attribute in a meta-annotation and the meta-annotation is not meta-present. However, the support for validating the configuration of @AliasFor in AnnotationUtils currently silently ignores such errors.

Deliverables

1. Ensure that an exception is thrown whenever a required meta-annotation is not present or meta-present on an annotation that declares an alias for an attribute in the meta-annotation.

Fixed in GitHub commit 8289036:

Throw exception if required meta-annotation is not present

It is a configuration error if an alias is declared via @AliasFor for an attribute in a meta-annotation and the meta-annotation is not meta-present. However, prior to this commit, the support for validating the configuration of @AliasFor in AnnotationUtils silently ignored such errors.

This commit fixes this by throwing an AnnotationConfigurationException whenever a required meta-annotation is not meta-present on an annotation that declares an explicit alias for an attribute in the meta-annotation.
