RESTEasy ViolationReport is not processed by JAXB provider ---------------------------------------------------------- Key: WFLY-4027 URL: https://issues.jboss.org/browse/WFLY-4027 Project: WildFly Issue Type: Bug Components: REST Affects Versions: 8.1.0.Final, 8.2.0.CR1, 9.0.0.Alpha1 Reporter: Harald Wellmann Assignee: Stuart Douglas Labels: resteasy, validation Fix For: 8.2.0.CR1, 9.0.0.Beta1 When used in combination with Bean Validation, RESTEasy should wrap validation errors in a {{ValidationReport}} which should be included in the REST response, marshalled to JSON or XML, depending on the content type. This does not work currently in WildFly 8.1.0.Final. The issue was reported in RESTEASY-1054. and is marked as fixed in RESTEasy 3.0.9.Final. However, I can still reproduce the issue with a local build of WildFly 8.2.0.CR1-SNAPSHOT (from the 8.x branch) which includes RESTEasy 3.0.10.Final. Going back to WildFly 8.1.0.Final, the issue no longer occurs when I add {code} <module name="javax.xml.bind.api"/> {code} to the {{module.xml}} descriptor of {{org.jboss.resteasy.resteasy-validator-provider-11}}. The same fix works for 8.2.0.CR1-SNAPSHOT. Looking at the module descriptor, it seems that 9.0.0.Alpha1 is also affected (but I did not test my sample on 9.0.0.Alpha1).
