Wildfly 13 to wildfly 17 json serialization ------------------------------------------- Key: WFLY-12239 URL: https://issues.jboss.org/browse/WFLY-12239 Project: WildFly Issue Type: Bug Components: Web Services Affects Versions: 17.0.0.Final Environment: I developear an EAR, with an EJB module and a Web module, that works perfectly on wildfly 13. I am trying to migrate to version 17.0.0.Final Reporter: Alfredo Marchini Assignee: Jim Ma Priority: Major Labels: jackson, json, serialization, yasson Fix For: 13.0.0.Final I have problem in serialization of Pojo to JSON. I have a Provider that impelments ContextResolver<ObjectMapper>. That constructor is called regulary on deploy, but the method getContext is never called, so my custom serialization registration is never called. What's changed at json serialization level between 13 and 17? If I copy yasson-1.0.1 from wildfly 13 and swap it with yasson-1.0.3 (wildfly 17) everything works fine. Thank you very much Regards
