title: cxf-java2ws-plugin generates an input parameter in wsdl for no input parameter method in java
body: <p>I am using cxf-java2ws-plugin version 3.1.12.
  The following method, which takes no input params,</p>
  
  <pre><code>    @WebMethod public @WebResult(name = "owner") Collection&lt;Owner&gt;  
           getAllOwners();
  </code></pre>
  
  <p>Results in the following wsdl part:
  .......
  .......</p>
  
  <pre><code>    &lt;wsdl:operation name="getAllOwners"&gt;
         &lt;wsdl:input name="getAllOwners" message="tns:getAllOwners"&gt;
         &lt;/wsdl:input&gt;
         &lt;wsdl:output name="getAllOwnersResponse"    
                 message="tns:getAllOwnersResponse"&gt;
         &lt;/wsdl:output&gt;
      &lt;/wsdl:operation&gt;
  </code></pre>
  
  <p>.......</p>
  
  <pre><code>    &lt;wsdl:message name="getAllOwners"&gt;
          &lt;wsdl:part name="parameters" element="tns:getAllOwners"&gt;
          &lt;/wsdl:part&gt;
      &lt;/wsdl:message&gt;
  </code></pre>
  
  <p>.......</p>
  
  <p>What can be done in order to generate the wsdl correctly (without input params)? </p>
