Mock Service Error With JSON

Hi:

I'm using SOAPUI Pro 3.5.1 to run a REST mock service using a groovy script in the OnRequest tab. When I send a normal XML POST request to the mock service, everything works fine. However, if I send a POST that has json content (application/json) the mock service returns this error:

HTTP/1.1 500 Internal Server Error
Content-Type: text/html; charset=iso-8859-1
Transfer-Encoding: chunked
Server: Jetty(6.1.x)

13B
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body>
<soapenv:Fault>
<faultcode>Server</faultcode>
<faultstring>org.apache.xmlbeans.XmlException: error: Unexpected element: CDATA</faultstring>
</soapenv:Fault>
</soapenv:Body>
</soapenv:Envelope>

Here is the error log:

I've tried this in 3.6 beta 2 with the same result. Please let me know if there is a workaround or if it can be fixed.

Thanks,
