    Description

      Smallrye OpenAPI throws a java.lang.NullPointerException when a war file is deployed which contains JAX-RS endpoint using Java Generics:

      The error was originally spotted running AnnotationInheritanceGenericsTest in the Resteasy test-suite with jboss-eap-xp-1.0.0.GA-CR1.zip.

      We attached 3 sample maven projects:

      • repro-generics: contains JAX-RS endpoints that contain generics and inheritance and you hit the java.lang.NullPointerException when you deploy it
      • repro-generics-no-inheritance: contains JAX-RS endpoints that contain generics (no inheritance) and you hit the java.lang.NullPointerException when you deploy it; this proves the problem is related to generics and not to the combination generics + inheritance (this was done because the AnnotationInheritanceGenericsTest test contains this combination)
      • repro-no-generics: contains the same JAX-RS endpoints as the first one but with no generics and you don't hit the error

      One workaround would be disabling OpenAPI from the application like described in Admin_Guide:

      in /META-INF/microprofile-config.properties:

mp.openapi.extensions.enabled=false

      Another workaround would be disabling OpenAPI at the server level:

      $ ./bin/jboss-cli.sh 
[disconnected /] embed-server --server-config=standalone-microprofile.xml
[standalone@embedded /] /subsystem=microprofile-openapi-smallrye:remove()

      Smallrye OpenAPI throws java.lang.NullPointerException in different cases. The first one which was reported is when a war file is deployed which contains JAX-RS endpoint using Java Generics but please see recent comments and relevant information in the "Steps to Reproduce" field in order to get latest details.

        Issue Links

          is incorporated by

          Component Upgrade - A task tracking an update to a bundled component or revision of component upstream of the project. JBEAP-19499 Upgrade smallrye-open-api from 1.1.21.redhat-00004 to 1.1.22.redhat-00001

          • Blocker - To be worked above all other priorities. This term is chosen when the severity of the issue is very high, has no workaround, or the effort for the change is comparatively low. Issues that may be very publicly visible and could generate significant media attention may also drive a higher priority.
          • Verified
          is related to

          Task - Represents a small unit of work that is not end-user facing. RESTEASY-2589 Check all the "ExpectedFailingBecauseOfSmallRyeMicroprofileOpenApi11" annotations after next SmallRye OpenAPI release

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
