Java Scheduled Executor: Does it guarantee to not run in paralell if task hast not yet finished
does anyone know if the following java Method in the java.util.concurrent Package `ScheduledExecutorService.html#scheduleAtFixedRate()`

absolutely guarantees, that the Runnable scheduled will never run in parallel in case the runnable from the "last" run did not yet finish:

For example (Pseudocode)

    1.00 o'clock: scheduleAtFixedRate(MyRunnable, "Run ever Hour")`
    //1.30 o'clock: MyRunnable Has finished (everthing is fine)
    2.00 o'clock: MyRunnable is triggered to run again
    3.00 o'clock: MyRunnable has NOT yet finished ==> What will happen here? 
    Will java Simply SKIP the starting of MyRunnable (as the old instance has not yet 
    finished) and try again at 4 o'clock or will Java start a NEW MyRunnable that then will 
    run in parallel to the "old" MyRunnable.

Thank you very much
