getWorklogs always returns empty array

[Manan]

Attempting to get the work log of an issues using getWorklogs() but it always return empty array even thou the issues have worklog.  Dumping the toString for issues display the below:

worklogs=[],

is there a special way to get the workLog for a given task.

Issue issueFromJira;

...

Iterable worklogs = issueFromJira.getWorklogs();

System.out.println("getWorklogs Size : " + Iterables.size(worklogs));
