Personally, I prefer having more explicit API and usually use a
self-scheduling job for this. This has the benefit of very clean API.

Job#schedule()
Job#cancel()

If the real Job isn't capable of self-scheduling you can wrap it like this:
Job realJob = ...;
Job schedulingJob = new Job("blah") {
  protected IStatus run(...) {
    // start real job
    realJob.schedule();

    // optionally wait for Job to finish
    realJob.join();

    // reschedule
    long bunchOTime= calculateSleepTime();
    schedule(bunchOTime);
    return Status.OK_STATUS;
  }
}.schedule();
