[midPoint] Event notifications for some resource modification only

Oleksandr,
it seems that embedded filters (your expressionFilter in this case) are
evaluated before so called quick applicability check is done for
simpleResourceObjectNotifier. So, your filter is invoked with all kinds
of events, not just with resource-related ones.
If you want it to work, you need to include either
"event.isCategoryType(com.evolveum.midpoint.xml.ns._public.common.common_3.EventCategoryType.RESOURCE_OBJECT_EVENT)"
or
"event instanceof
com.evolveum.midpoint.notifications.api.events.ResourceObjectEvent"
before calling event.getResourceName().
If I would have a bit of time I would try to improve this event handling
code. But ... it's a question of priorities.
Best regards,
