Found an issue while testing compatibility between 6.5 Kie server and 6.4 client. Server error is listed in attachment.
Issue happens when I try to call KieServicesClient.listContainers() using JMS with XSTREAM marshalling.

To reproduce issue see [1].
It seems to be related to filtering for listContainers [2].
