When you enable logging of org.hibernate.SQL the log is not send to the log4j loggers/appenders.
The reason for that is a null pointer exception in:
Class: 
Log4j2Logger
Method:
protected void doLog(final Level level, final String loggerClassName, final Object message, final Object[] parameters, final Throwable thrown) {
Line: 
50 

{code:title=Log4j2Logger.java|borderStyle=solid}
    @Override
    protected void doLog(final Level level, final String loggerClassName, final Object message, final Object[] parameters, final Throwable thrown) {
        final org.apache.logging.log4j.Level translatedLevel = Log4j2Logger.translate(level);
        if (this.logger.isEnabled(translatedLevel)) {
            try {
                this.logger.log(null, loggerClassName, translatedLevel,
                        parameters == null || parameters.length == 0 ? this.messageFactory.newMessage(message) :
                                this.messageFactory.newMessage(String.valueOf(message), parameters),
                        thrown);
            } catch (Throwable ignored) { }
        }
    }
{code}


This  this.logger.log call is the one causing NPE which is ignored .. because of the surrounding catch.

If you change the call to something like : 

{code:title=Example (params are not passed but you can pas them as well )|borderStyle=solid}
this.logger.log(translatedLevel,this.messageFactory.newMessage(String.valueOf(message), thrown)
{code}

As an example you will see its working.
