it seems that some versions of Hibernate are broken
* 5.2.12.Final = GOOD
* 5.2.13.Final = GOOD
* 5.2.14.Final = Exception
* 5.2.15.Final = Exception
* 5.2.16.Final = Exception
* ?
i create test to reproduce https://github.com/evg345/hibernate-test-case-templates/blob/master/orm/hibernate-orm-5/src/test/java/org/hibernate/bugs/HHH12436/OneToOnePropertyTestCase.java
and make pulll request also |
