Hibernate logger does not replace %s

I noticed for a while now that hibernate does not replace %s templates in log messages. Our own log message are replaced fine. My project uses spring boot (slf4j + logback included).

Hibernate info at server start looks like this:

Other libs are affected as well:

Solution
    • To configure hibernate to use slf4j, it need the following property , it need either starting the application with
        -Dorg.jboss.logging.provider=slf4j

    or in the Main Spring boot application class

        static { 
        System.setProperty("org.jboss.logging.provider", "slf4j");
    }

    Steps taken to figure out what went on

    This is not actually an answer but some steps to troubleshoot as one of the classes above is JtaPlatformInitiator as I can't replicate it.

    • Put a breakpoint in the class JtaPlatformInitiator.org.hibernate.engine.transaction.jta.platform.internal at the following line:
        LOG.usingJtaPlatform( platform != null ? platform.getClass().getName() : "null" );

    • When the application starts, it is going to come to the above line.

    • Then it will reach this jboss class and you can see the unformatted string as well as params. enter image description here

    • Now once you go inside this method, it should be choosing one of them and prepare one formatted string. For me, it went to org.jboss.logging.Log4j2Logger and is concatenating correctly.

    • Can you check what class selected for you in the last step?
