This is a small reproducer project for Quarkus issue #21173.

./mvnw compile quarkus:dev

Download and open (or display in browser) http://localhost:8080/q/openapi

• The operation in path /adress carry the Address Resource tag.
• The operation in path /person carry the Person Resource tag.

There is a dedicated unit test for this, which can be executed using:

./mvnw test -Dtest=AddressResourceTest#testTagInOpenApi
