How to process node move event with EventListener in AEM? Duplicate calls occurs

I have service that implements javax.jcr.observation.EventListener. This service is listening the following event types:

Event.NODE_MOVED

Event.NODE_REMOVED

When I move node myCustomCodeToExecute() method is triggered twice.

Is there a way to trigger my code only once if someone moves node?

    executor.submit(() -> {

        List<Event> eventsList = IteratorUtils.toList(eventIterator);

        for (final Event event : eventsList) {

            try {

                myCustomCodeToExecute()

            } catch (Exception e) {

                LOGGER.error("Can't send event", e);

            }

        }

    });

REMOVE event works as expected

I think you might be adding multiple/multi-level nodes causing multiple events to be emitted. try printing event.getInfo() and see if thy are same.

@awd both executions a relative to the same node. I have moved a leaf, there is no multi-level depth.

I found an solution:

@Override

public void onEvent(EventIterator eventIterator) {

    executor.submit(() -> {

        List<Event> eventsList = IteratorUtils.toList(eventIterator);

        for (final Event event : eventsList) {

            try {

                if (eventType == Event.NODE_REMOVED) {

                    if (eventsList.stream().noneMatch(e -> Event.NODE_MOVED == e.getType())) {

                         //remove event

                    }

                         //move event will be processed in next iteration

                         continue;

                    }

                }

            } catch (Exception e) {
