I just realized that event.getMessage() print "{}", so I 've decided to replace event.getMessage by event.getFormattedMessage(). And the two outputs Debug are printed because one of them belongs to event.getLevel(), the other one belongs to the log level from xml file that is also set as Debug.<logger name="Company_Module" level="debug"/> Thanks for you quick reply.

The curly braces should not appear in the log message at all, they are placeholders for the toString substitutions of the arguments. The other confusing thing to me is the multiple DEBUG outputs. Is there any chance that what you are looking at is someone's wrapper around straight-up SLF4J? It would be helpful if you could show your source with at least the imports and maybe your logback.xml configuration as well.
