Mock sending extra characters after header

Hi,

We have defined this response to be delivered by our mock:

<s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope">
   <s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
      <getChargePointInfoResponse xmlns="urn://Vas/Cs/2010/12/"></getChargePointInfoResponse>
   </s:Body>
</s:Envelope>

And this is what we see as raw response when querying that mock from SoapUI:

HTTP/1.1 200 OK
Content-Type: application/soap+xml;charset=UTF-8
Content-Encoding: gzip
Transfer-Encoding: chunked
Server: Jetty(6.1.x)

<s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope">
   <s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
      <getChargePointInfoResponse xmlns="urn://Vas/Cs/2010/12/"></getChargePointInfoResponse>
   </s:Body>
</s:Envelope>

So far so good... But our system which was running against that mock was seeing some extra characters there which caused problems so I investigated inside SoapUI with http log and this is what I saw:

Note those two lines with "B" in them, after the header, right before XML code starts. Where are those coming from? I can see that they depend on the actual size of message being sent and is most probably hexadecimal number. So what can we do about this???

Thanks,
