Suggested fix is to have Agent be more flexible when unmarshalling OR publications by ignoring such errors:
{{xStream.ignoreUnknownElements();}}

> Priority: Major
> Fix For: 3.0.1-Ducc

>
> If a new field is added in OR publication, for example to communicate information from OR to RM that is not needed by Agent, an older Agent will unnecessarily take an exception when trying to unmarshal a more recent OR deployment.
> Example Agent log:
> ---- Debugging information ----
> message : No such field org.apache.uima.ducc.transport.event.common.DuccSchedulingInfo.machineList
> field : machineList
> class : org.apache.uima.ducc.transport.event.common.DuccSchedulingInfo
> required-type : org.apache.uima.ducc.transport.event.common.DuccSchedulingInfo
> converter-type : com.thoughtworks.xstream.converters.reflection.ReflectionConverter
> path : /org.apache.uima.ducc.transport.event.DuccWorkReplyEvent/dw/duccSchedulingInfo/machineList
> class[1] : org.apache.uima.ducc.transport.event.common.DuccWorkJob
> class[2] : org.apache.uima.ducc.transport.event.DuccWorkReplyEvent
