There appear to be two approved ways of getting a JIRA Manager object in code:

1. Declare the Manager as a parameter in your constructor:

   public class MyComponent {
   
     private worklogManager;
   
     public MyComponent(WorklogManager worklogManager, ....) {
       this.worklogManager = workflowManager;
      ....
     }
      ....
   }
   

2. Call ComponentManager.getXxxManager.

If this is the case, then on each release we should make sure that all Managers are exposed through ComponentManager.
