Steps to reproduce (Only for bug reports)

1 -** Create a basic JAX-RS application with a simple class with @get and @QueryParam:

@Path("/test")
@Consumes({MediaType.APPLICATION_JSON})
@Produces({MediaType.APPLICATION_JSON})
public class TestService {
    private static final String START_PAGE = "1";
    @GET
    public List<String> getProdutos(@QueryParam("page") int page) {
        return new ArrayList<String>();
    }
}

2 -** Create a class that extends org.glassfish.jersey.server.ResourceConfig with a default constructor and register any component:

@ApplicationPath("/")
public class ApplicationServices extends ResourceConfig {
public ApplicationServices() {
    packages("br.com.fabioluis.openapipayara5183error.services");

    // https://jersey.github.io/documentation/latest/security.html#d0e12436
    register(RolesAllowedDynamicFeature.class);

    // https://jersey.github.io/documentation/latest/declarative-linking.html
    register(DeclarativeLinkingFeature.class);

    // https://jersey.github.io/documentation/latest/media.html#json.moxy
    register(MoxyJsonFeature.class);

    // https://jersey.github.io/documentation/latest/media.html#d0e8809
    register(MoxyXmlFeature.class);

    // https://jersey.github.io/documentation/latest/entity-filtering.html
    // Register the EntityFilteringFeature.
    register(EntityFilteringFeature.class);
    }
}

3 -** Deploy the war and point you browser to http://localhost:8080/openapi

Samples

Project: openapi-payara-5183-error.zip

Context (Optional)

To the problem occur we need two premisses:

1 -** At least one registered component in the ResourceConfig extended class constructor.
2 -** At least one method annotated with @get and one @QueryParam in that same method

Hi @silvafabio,

This bug is caused by registering a Jersey provider, which causes the getClasses() method on the class to only return the providers registered. This information is used in generating the endpoint paths, and therefore causes the operation context to be null. I've made a pull request to address this issue which you can find here. Feel free to test that this fixes your issue. This fix will be included in 5.184.

Kind regards,

Matt

Hi @silvafabio,

Since a fix has been merged, I'll close this issue.

Kind regards,

Matt
