HHH000270: Type registration [java.util.UUID] overrides previous

Question

In an Hibernate 5 project, I’m getting the following warning during startup:

[org.hibernate.type.BasicTypeRegistry] HHH000270: Type registration [java.util.UUID] overrides previous : org.hibernate.type.UUIDBinaryType@53ec41aa

What causes this, and how can I avoid it?

The application is running fine; however, I wish to reduce the amount of messages, especially warning-like ones, that an application (even at INFO loglevel) throws at normal startup.

Answer 1

I had the same issue, there no errors, the process just stopped there. This happens when some process is currently using the database, when you try to regenerate the tables.

So basically just kill your application
