The property hibernate.hbm2ddl.auto is set to VALIDATE but it should not. Db structure does not need to be validated :
- only a few tables are still mapped as Hibernate entities
- executes a potental long SQL request : http://sonarqube.15.x6.nabble.com/Cleaning-snapshot-takes-too-long-tp5023299p5023807.html
- db structure is created by SQ. We can assume users don't change it.
