title: Supply Long Object Pool to Jackson Object Mapper
body: <p>I have a JSON that I convert into POJOs. The JSON is read from a GZIPInputStream <code>gis</code>. </p>
  
  <pre><code>ObjectMapper mapper = new ObjectMapper();
  
  TypeReference&lt;Map&lt;Long, ConfigMasterAirportData&gt;&gt; typeRef =
                  new TypeReference&lt;Map&lt;Long, ConfigMasterAirportData&gt;&gt;() {};
  
  Map&lt;Long, ConfigMasterAirportData&gt; configMasterAirportMap = 
                  mapper.readValue(gis, typeRef);
  </code></pre>
  
  <p>I do not want new <code>Long</code> objects to be created for each entry. I want it to get <code>Long</code> objects from a custom <code>LongPool</code> I have created. Is there a way to pass such a <code>LongPool</code> to the mapper?</p>
  
  <p>If not, is there another JSON library I can use to do that?</p>
