Additionaly I've tested same case in clear Hibernate ORM 5.2.13.Final (sources in hibernate-test-case-templates.zip class ORMUnitTestCase)
Here is result:

Hibernate ORM also convert Date to Timestamp, and equility fails after saveAndGet

That's why I think test in Neo4j is incorrect.

Also I've tested my current solution(repository link) on Infinispan, and all tests are success.

My conslusion is to fix test in Neo4j(change equal logic or objects creation)
Davide D'Alto I need a desigion on this issue, I can not move further
