title: Switch off java.langObject initialization in podam
body: <p>I have POJOs:</p>
  
  <pre><code>class PersonJob {
  
  private PersonAddress address;
  
  //a buch of fields (non Object type)
  }
  
  class PersonAddress extends AbstractContact {
  //empty fields class
  }
  
  class AbstractContact {
      private Object contactId;
  
      public Object getContactId() { return this.contactId }
  
      public void setContactId(Object contactId) {this.contactId = contactId}
  }
  </code></pre>
  
  <p>AbstractContact class is placed in external library.</p>
  
  <p>I'm using PodamFactory with my DataProvider which extending AsbractRandomDataProviderStrategy for filling PersonJob. But when JAXB serializes it I git such error:</p>

  <p>Is there a way to switch off instantiation of contactId field for AbstractContact class through DataProvider which extending AsbractRandomDataProviderStrategy?</p>
