[Apiman-user] CORS preflight OPTIONS request requires Authorization header

I have an API provisioned on APIMAN with Keycloak OAuth Policy and CORS Policy (using APIMAN Plugins) . Onclient side, I get the JWT token from Keycloak and add authorization header to get request sent to APIMAN for my own API. Problem is that APIMAN rejects OPTIONS preflight with 401 Unauthorized with message "OAuth2 'Authorization' header or 'access_token' query parameter must be provided." I am using APIMAN 1.2.7_final . I applied workaround in the JIRA issue given below but it didn't work for me. Does it work for both APIMAN's own rest endpoints and my own API's. I suppose it is not valid for the later one. http://lists.jboss.org/pipermail/apiman-user/2016-July/000727.html https://issues.jboss.org/browse/APIMAN-1209 TOKEN REQUEST TO KEYCLOAK General Request URL:http://localhost:8280/auth/realms/company/protocol/openid-connect/token Request Method:POST Status Code:200 OK Remote Address:127.0.0.1:8280 Response Headers Access-Control-Allow-Credentials:true Access-Control-Allow-Origin:http://localhost:8080 Access-Control-Expose-Headers:Access-Control-Allow-Methods Connection:keep-alive Content-Length:3175 Content-Type:application/json Date:Thu, 25 Aug 2016 07:22:59 GMT Server:WildFly/10 X-Powered-By:Undertow/1 Request Headers Accept:*/* Accept-Encoding:gzip, deflate Accept-Language:tr-TR,tr;q=0.8,en-US;q=0.6,en;q=0.4 Connection:keep-alive Content-Length:78 Content-Type:application/x-www-form-urlencoded Host:localhost:8280 Origin:http://localhost:8080 Referer:http://localhost:8080/login-services/login.html User-Agent:Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.103 Safari/537.36 Form Data view source view URL encoded username:username password:pasword grant_type:password client_id:company GET REQUEST TO API on APIMAN General Request URL:http://localhost:8280/apiman-gateway/client/test-services-ws/1.0/getuser/ Request Method:OPTIONS Status Code:401 Unauthorized Remote Address:127.0.0.1:8280 Response Headers Connection:keep-alive Content-Type:application/json Date:Thu, 25 Aug 2016 07:22:59 GMT Server:WildFly/10 Transfer-Encoding:chunked X-Policy-Failure-Code:11005 X-Policy-Failure-Message:OAuth2 'Authorization' header or 'access_token' query parameter must be provided.
