[jboss-jira] [JBoss JIRA] (WFLY-1605) Jackson type info is lost in a GET request returning a collection of objects

[Juergen Zimmermann (JIRA)]

     [ https://issues.jboss.org/browse/WFLY-1605?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Juergen Zimmermann updated WFLY-1605:
-------------------------------------

    Attachment: testcase-WFLY-1605.zip


The test class contains 2 test methods
1) The method "failure" tests the URL according to a GET method which returns a Response object (containing a list of objects) and fails because of the lost type info
2) The method "success" tests the URL according to a GET method which directly returns a list of objects

> 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.
