title: Dozer - empty object instead of null
body: <p>In dozer how do i globally initialize values to empty object instead of null</p>
  
  <p>For ex:</p>
  
  <pre><code>Class Person
  {
  public Address address;
  //getters and setters for address
  
  }
  
  Class Address
  {
  String addressField1;
  String addressField2;
  }
  </code></pre>
  
  <p>Similarly I have objects PersonVO and AddressVO which are similar to Person and Address</p>
  
  <p>After mapping the values using the dozer, if address value is null in Person object, than the result in <code>personvo.getAddressVO.getAddressField1()</code> will throw <em>null pointer exception</em>, is there any way to avoid this?</p>
  
  <p>If I use custom converters than i would end up in doing typical way of setting values in custom converters and would defeat the purpose of using the dozer.</p>
