Webhooks not rendered in generated spec

[mark-roy]

I have a project that I have been successfully generating openapi.json using Swagger annotations v2.2.22. I've taken the @webhooks example from modules/swagger-jaxrs2/src/test/java/io/swagger/v3/jaxrs2/petstore/WebHookResource.java and added it to my project, but have not been able to get webhooks rendered in the spec file.

I've debugged the decompiled code to this point in SpecFilter, where the resourcePath is "webhook2" (from the example hook). The code then does a 'get' on that resource path and gets null on return, which it passes on to filterPathItem. Eventually this results in a NullPointerException.

            if (filteredOpenAPI.getWebhooks() != null) {
                Iterator var18 = filteredOpenAPI.getWebhooks().keySet().iterator();

                while(var18.hasNext()) {
                    String resourcePath = (String)var18.next();
                    pathItem = (PathItem)filteredOpenAPI.getPaths().get(resourcePath);
                    filteredPathItem = this.filterPathItem(filter, pathItem, resourcePath, params, cookies, headers);
                    PathItem clonedPathItem = this.cloneFilteredPathItem(filter, filteredPathItem, resourcePath, params, cookies, headers, allowedTags, filteredTags);
                    if (clonedPathItem != null && !clonedPathItem.readOperations().isEmpty()) {
                        clone.addWebhooks(resourcePath, clonedPathItem);
                    }
                }
            }

Do I need to define a @path("webhook2") somewhere? The example code doesn't seem to.
