Jackson type info is lost in a GET request returning a collection of objects ---------------------------------------------------------------------------- Key: WFLY-1605 URL: https://issues.jboss.org/browse/WFLY-1605 Project: WildFly Issue Type: Bug Components: REST Affects Versions: 8.0.0.Alpha2 Reporter: Juergen Zimmermann Assignee: Stuart Douglas Attachments: testcase-WFLY-1605.zip I'm having a simple class hierarchy: an abstract class AbstractCustomer and 2 derived concrete classes. 1) When the GET request's method directly returns a list of objects of AbstractCustomer, then the mapping information is available (as defined with @JsonTypeInfo and @JsonSubTypes) 2) However, when the GET request's method returns a Response object encapsulating the same list (plus a link header), then the mapping information isn't sent to the client. I'll attach a testcase.
