[jboss-jira] [JBoss JIRA] (WFLY-13559) Header response has changed and missing fields

Header response has changed and missing fields ---------------------------------------------- Key: WFLY-13559 URL: https://issues.redhat.com/browse/WFLY-13559 Project: WildFly Issue Type: Bug Components: MP OpenTracing Affects Versions: 19.0.0.Final, 19.1.0.Final, 20.0.0.Final Reporter: Alexandru Ciouca Assignee: Emmanuel Hugonnet Priority: Major Fix For: 21.0.0.Beta1 Attachments: standalone_18.0.0.final.xml, standalone_19.1.0.final.xml, test-endpoint-BEANS-XML.war, test-endpoint-CONTEXT.war, test-endpoint-WORKING.war I have an application running in WildFly with some open endpoints to call and I tried an upgrade to WildFly 19.1.0.final from 18.0.0.final, but I noticed that something changed when calling the endpoints. In the Response Header I see that some of the fields are changed or are missing. Is this supposed to happen or do I need to add some extra configuration with WildFly 19? Response WildFly 18.0.0.final: {code} HTTP/2 500 cache-control: no-store, no-cache, must-revalidate set-cookie: JSESSIONID=pLpPEvZZVekh0Bkqq06muz_cJ4_fmwxsqrt0HUdP.myservices-container-6f5b87f79d-ngzhf; path=/myservices access-control-allow-headers: origin, content-type, accept, X-XSRF-TOKEN content-type: application/json content-length: 182 link: <http://test.com/afs/rest>; rel="profile" date: Thu, 04 Jun 2020 07:34:10 GMT set-cookie: 7951a12696148c7a83e36db56eeb5f91=5ede0885e2c831c4946125e91d3facba; path=/; HttpOnly; Secure strict-transport-security: max-age=31536000; includeSubdomains x-xss-protection: 1; mode=block x-content-type-options: nosniff x-frame-options: SAMEORIGIN {code} Response WildFly 19.1.0.final: {code} HTTP/2 200 set-cookie: JSESSIONID=9siDVU14OoFXojIIVxlMWbxNg1gcuSmLokwamY29.myservices-container-7c8dbf55f5-ctcks; path=/myservices content-type: application/json content-length: 182 date: Thu, 04 Jun 2020 07:27:57 GMT set-cookie: 7951a12696148c7a83e36db56eeb5f91=3edfc7a7549d107b41669532f6cb594a; path=/; HttpOnly; Secure cache-control: private strict-transport-security: max-age=31536000; includeSubdomains x-xss-protection: 1; mode=block x-content-type-options: nosniff x-frame-options: SAMEORIGIN {code} As you can see the first thing that changed is the response code, even though the code is the same for both versions. The cache-control is also different and access-control-allow-headers and link fields are missing. I am attaching also the standalone.xml for both versions.
