Arun C. Murthy agrees that when > possible it is preferable to program against the interface rather than a > concrete implementation (more flexible, allows for changes of the > implementation in future etc.) JobControl currently exposes running, waiting, > ready, successful and dependent jobs as ArrayList rather than List. I propose > to change this to List. > I will code up a patch for this. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
