Problem:
On WebLogic 12.2.1, which is using JAX-RS 2.0, the REST API and Webapp have problems to correctly serialize complex objects. This does not affect all objects and requests. WebLogic comes with Jersey v2.21.1.
Check the following examples how the bug manifests.
Following request works:
http://localhost:7001/engine-rest/task
Returns:
