      Request to backport JBPM-5133 and JBPM-5189 to 6.4.z

      RESTWorkItemHandler does not allow for charset encodings other than HTTPClient default of ISO 8859-1. This is an invalid encoding for application/json payloads, and causes parsing errors when sending UTF-8 characters.

      RESTWorkItemHandler needs to pattern match on Content-Type to select JSON or XML payload (instead of strict equality), and needs to forward charset parameter to HTTPClient.
