Tomas Lamr could you test the PR I pushed here: https://github.com/hibernate/hibernate-orm/pull/2638

git clone https://github.com/gsmet/hibernate-orm.git
cd hibernate-orm
git checkout HHH-13097

You should be able to push the SNAPSHOT artifacts to your local Maven repo with:

./gradlew clean build publishToMavenLocal -x test 

It would be nice if we could have the feedback today as I plan to release 5.4.0.CR1 tomorrow.

Thanks!
