Web Application Exception in the Log

i have this start to what is pretty long error in my log. Not sure what triggers it. From some searches, looks like it was noted as far back as 2012 but not finding any recent info. I also found where it might be related to the java calls in the rules? I’m running 1.8.3.

Here is the short start and I can post more if needed:

javax.ws.rs.WebApplicationException: javax.xml.bind.MarshalException

  • with linked exception:
    [javax.xml.stream.XMLStreamException: org.eclipse.jetty.io.EofException]
