It seems, that code change introduced in #1959 doesn't work correctly on JDK 11 (17 and 21 works). It's about following line Map visitedObjects = new IdentityHashMap(values.stream().collect(Collectors.summingInt(Set::size))); Issue is presented by following EL test error: NestedUnitOfWorkDeleteNestedNewObjectTest Exception Description: Fatal error occurred. Internal Exception: java.lang.ClassCastException: class java.lang.Integer cannot be cast to class java.util.Map (java.lang.Integer and java.util.Map are in module java.base of loader 'bootstrap') Local Exception Stack: Exception [EclipseLink-0] (Eclipse Persistence Services - 2.7.14.qualifier): org.eclipse.persistence.testing.framework.TestErrorException Exception Description: Fatal error occurred.

Test itself should be called with any JDK (11, 17, 21). Origin lambda is refactored into more "classical" style. Signed-off-by: Radek Felcman <radek.felcman@oracle.com>
