@suztomo So google-cloud-notification depends on storage and pubsub. In this case, to fix this, we wait for storage and pubsub to release with the new shared-dependencies first, then update here. Am I understanding this right?
Update: storage is not releasing with shared-dependencies 3.12.0. Should we temporary exclude j2objc-annotations from storage as in googleapis/sdk-platform-java#1791? What do you think? Watch for storage 2.22.5 release

Should we temporary exclude j2objc-annotations from storage as in googleapis/sdk-platform-java#1791? What do you think?

The temporary exclusion makes sense.
