OK. Here attached is the new test case: HHH-9473-TEST.zip
Uncompress the archive and launch the tests with Maven. There are three Maven profiles for the three versions of hibernate which I tested (3,4,5):

$ mvn -P hibernate5 clean test
...
Tests run: 2, Failures: 0, Errors: 0, Skipped: 0
...
$ mvn -P hibernate4 clean test
...
Tests run: 2, Failures: 0, Errors: 0, Skipped: 0
...
$ mvn -P hibernate3 clean test
...
Tests run: 2, Failures: 0, Errors: 0, Skipped: 0
...

The class containing the two tests is it.unipg.jira.hibernate.Test

Best regards.
