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

Multi tool use
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 printingevent.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.

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) {
