[jboss-jira] [JBoss JIRA] (WFLY-13397) MP HeaderPropagation does not propagate headers

MP HeaderPropagation does not propagate headers ----------------------------------------------- Key: WFLY-13397 URL: https://issues.redhat.com/browse/WFLY-13397 Project: WildFly Issue Type: Bug Affects Versions: 19.0.0.Final Reporter: Thimo König Assignee: Brian Stansberry Priority: Major Attachments: mp-headerpropagation-1.0.0-SNAPSHOT-sources.jar, mp-headerpropagation-1.0.0-SNAPSHOT.war, openliberty_response.json, wildfly_response.json When calling a JAX-RS Resource from another JAX-RS Resource using the MP RestClient the propagation of headers does not work. I have created a sample app which is available on github https://github.com/koenigt/headerpropagation and attached [^mp-headerpropagation-1.0.0-SNAPSHOT.war] to this report aswell. Deploy the sample app and use CURL like: {code} curl -i -H "Accept: application/json" -H "Header2Propagate: PropagatedValue" http://localhost:8080/mp-hp/api/client {code} The expected result should be: {code:JSON} { "Name": "ClientResource", "org.eclipse.microprofile.rest.client.propagateHeaders": "Authorization,Accept-Language,Header2Propagate", "IncomingRequestHeaders": { "Accept": "[*/*]", "accept-encoding": "[gzip, deflate, br]", "Cache-Control": "[no-cache]", "connection": "[keep-alive]", "Content-Type": "[null]", "Header2Propagate": "[PropagatedValue]", "Host": "[localhost:9080]", "Postman-Token": "[8105e2ef-9b5f-4b3f-a7a9-cea73d51efee]", "User-Agent": "[PostmanRuntime/7.24.0]" }, "ServerResponse": { "Name": "ServerResource", "IncomingRequestHeaders": { "Accept": "[application/json]", "Cache-Control": "[no-cache]", "connection": "[keep-alive]", "content-type": "[application/json]", "Header2Propagate": "[PropagatedValue]", "Host": "[localhost:9080]", "MyClientHeader": "[newHeaderValue]", "Pragma": "[no-cache]", "User-Agent": "[Apache-CXF/3.3.3-SNAPSHOT]" } } } {code} but since the header is not propagated you are getting only this: {code:JSON} { "Name": "ClientResource", "org.eclipse.microprofile.rest.client.propagateHeaders": "Authorization,Accept-Language,Header2Propagate", "IncomingRequestHeaders": { "Accept": "[*/*]", "Accept-Encoding": "[gzip, deflate, br]", "Cache-Control": "[no-cache]", "Connection": "[keep-alive]", "Header2Propagate": "[PropagatedValue]", "Host": "[localhost:8080]", "Postman-Token": "[6e36736f-3b55-4f34-9f39-063dbd4f4e8f]", "User-Agent": "[PostmanRuntime/7.24.0]" }, "ServerResponse": { "Name": "ServerResource", "IncomingRequestHeaders": { "Accept": "[application/json]", "Connection": "[Keep-Alive]", "Host": "[localhost:8080]", "User-Agent": "[Apache-HttpClient/4.5.11 (Java/12)]", "uber-trace-id": "[a0d9d0ac4c54614%3Ac82190f35d41f958%3Aa0d9d0ac4c54614%3A1]" } } } {code} This issue has already been discussed on https://groups.google.com/forum/#!topic/wildfly/QOx3AfrXAMc and Rebecca Searls (rseals(a)redhat.com) ask me to file this bug report
