mock service 500 error

Running a mock service.  Sending requests is returning 500 server error.  Nothing in log.  How to debug?

If I call soap mock serivce directly from soapui, get this:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body>
<soapenv:Fault>
<faultcode>Server</faultcode>
<faultstring>java.lang.Exception: No signature of method: static java.lang.Math.Random() is applicable for argument types: () values: []
