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.
