Commit indexing on 5.x releases sometimes fails with a set of errors like this:

This appears to be related to the upgrade to Hibernate 5.2.10, which has had some bugs reported related to how inserts and updates are ordered. While those bugs have been fixed, a Hibernate 5.2.11 release including them has not yet been finalized. Bitbucket Server should work around the ordering problems by using Session.flush() to force the correct order.
