title: spring JNDI logging before logback is initialized
body: <p>I've got a spring boot app that is outputing around 1500 lines of JNDI debug logging to stdout at startup before logback is initialized. Does anyone know what's causing this and if there is a way to get logback initialized before this? I've got -Dlogback.debug=true but it doesn't help much.</p>
