Resolutiondate missing from Issue class for JRJC client?

[Jay Guidos]

I am using the JRJC client with this maven GAV:

<dependency>
   <groupId>com.atlassian.jira</groupId>
   <artifactId>jira-rest-java-client-core</artifactId>
   <version>5.1.0</version>
 </dependency>

 <dependency>
   <groupId>com.atlassian.jira</groupId>
   <artifactId>jira-rest-java-client-api</artifactId
   <version>5.1.0</version>
 </dependency>

As of version 5.1.0, it appears that com.atlassian.jira.rest.client.api.domain.Issue does not parse and provide a getter API method for resolutiondate.  I realize that there should be no setter for that field, as the resolution date should be set during a transition, but resolutiondate is present in the REST payload when you get an issue.

Was this omitted from Issue by a simple oversight?  Or is there a reason why you are avoiding that field, and there is some other way to get the resolutiondate properly?
