Hibernate: Clean collection's 2nd level cache while cascade delete items

Question

I have a problem Hibernate does not update 2nd level cache for a collection of items which are subject of cascade removal.

Details

Assume we have an object Par

Answer 1

Usually Hibernate need a politically incorrect refresh of the object to reload the cahe.

An important thing is how that EhCache handles the lazy properties. I found that the lazy attribute of the collection is not set, the cahe doesn't refresh the objects.

In your case, If the Humans set of the humanity attribute is set to lazy = true (default option), ehcache doesn't refresh it if the object. Try to set the lazy attribute of the humans and children collections to false.
