Jackson Annotations are broken ------------------------------ Key: WFLY-10781 URL: https://issues.jboss.org/browse/WFLY-10781 Project: WildFly Issue Type: Bug Components: REST Affects Versions: 13.0.0.Final Environment: Windows 10 x64, WildFly 12 & 13 Reporter: Mario-Luca Hoffmann Assignee: Alessio Soldano Labels: jackson With the switch from WildFly 12 to 13 our Jackson Annotations stopped working properly. While some of these are working (@JsonProperty) sometimes, others (@JsonIgnore) aren't working anymore. With WildFly 12 everything is fine, this issue only arises using WildFly 13 using a EE8 profile. However, I tried it with a pristine WildFly 13: not working, WildFly 12: works like a charme. I tried to fix it with replacing the jackson-databind library with the newest version (2.9.6) but this didn't work as well. Example for the attached Github Project: The expected output is: {"name":"Mario","attribute":"notWorking"} The acutal output is: {"attribute":"notWorking","name":"Mario","number":-1337}
