We noticed that during application deployment, all relevant Hibernate persistence units are getting created 2 times, thus significantly increasing deployment time.

Attached is a relevant log from a deployment and a demo war to reproduce the issue

Tested with Hibernate > 5.2.11. Currently: 5.4.16

Reproduce Actions

Actions :

1. create new data source in weblogic with jndi name: *jdbc/SSA*  Use oracle db.
2. deploy app
3. check logs

You will notice that the log entry:
Processing PersistenceUnitInfo \[name: primary]

happens 2 times\!\!
