title: Issue on json parsing
body: <pre><code>String jsonMessage = mapper.writeValueAsString(m);
  </code></pre>
  
  <p>The type com.fasterxml.jackson.core.<code>JSonprocessingException</code> cannot be resolved it is indirectly referenced by a .class.</p>
  
  <p>I tried to update it with pom of jackson 
  
  <pre><code>https://mvnrepository.com/artifact/org.codehaus.jackson/jackson-mapper-asl --&gt;
  &lt;dependency&gt;
      &lt;groupId&gt;org.codehaus.jackson&lt;/groupId&gt;
      &lt;artifactId&gt;jackson-mapper-asl&lt;/artifactId&gt;
      &lt;version&gt;1.9.9&lt;/version&gt;
  &lt;/dependency&gt;
  
  
   // avoid too much magic and transform ourselves
    ObjectMapper mapper = new ObjectMapper(); 
   //mapper.writeValueAsString(m);
    String jsonMessage =mapper.writeValueAsString(m.toString()); 
  </code></pre>
  
  <p>Actual it must not show error on line</p>
