Cool :)

If you have a little bit time, would you mind to send PR and add this 
info to the README of our quickstart: 
https://github.com/keycloak/keycloak-quickstarts/blob/latest/user-storage-jpa/README.md 
? Maybe add some small note to the last "More Informations" section or 
create new "Troubleshooting" section in the end?

Thanks,
Marek
