Hi,

I am using swagger-core 2.0 with jersey JAX-RS-2.0 in order to generate REST API's specifications. I have integrated swagger 2.0 with JAX-RS by following the steps given in-

https://github.com/frantuma/swagger-core/wiki/Swagger-2.X---Integration-and-configuration

and I have also configured custom OpenAPI scanner to scan my resources. I have build a separate EAR having my custom scanner provided with all the libraries required to work with my application. But when I am trying to deploy the EAR I am getting following error in the server logs-

<May 11, 2018 11:43:54,161 AM UTC> <Error> <HTTP> <BEA-101017> <[ServletContext@1774997470[app:SwaggerEar module:swagger path:null spec-version:3.1]] Root cause of ServletException.
