Error when using Java 8 LocalDateTime in JSON format with the REST API in Intelligent Process Server 6

Issue

When using LocalDateTime in a model object used to start a process in JSON format, for example:

{
  "myObj" : { "example.MyObj": { "time" : "2017-02-27T17:25:18.805" } }
}

We have the following exception:

ERROR [org.kie.server.remote.rest.jbpm.ProcessResource] (http-127.0.0.1:8180-1) Unexpected error during processing Error unmarshalling input: org.kie.server.api.marshalling.MarshallingException: Error unmarshalling input

Is this possible to use LocalDateTime with Kie Server in BPM Suite 6?
