Ensure at least one subtask is associated before issue closed

Question

Since we don't have the ability to auto create subtasks for specific issue types due to limitations being an OnDemand user, does anyone have suggestions on how we can not allow closure of an issue if there is not at least one subtask associated with it?

There is no existing JIRA workflow components that make sure atleast one subtask is there. So this can't be done in onDemand.
