title: slf4j trace vs debug used with log4j
body: <p>From the log4j documentation I know that these are the levels in the h <a href="http://logging.apache.org/log4j/1.2/manual.html" rel="nofollow">http://logging.apache.org/log4j/1.2/manual.html</a></p>
  
  <p>TRACE,
  DEBUG,
  INFO,
  WARN,
  ERROR and
  FATAL</p>
  
  <p>Fatal being the top level. But could not understand the difference between Trace and  debug. I have tried with setting the log level to debug and I can see the trace messages. But when I set the log level to trace I cannot see the debug messages.</p>
  
  <p>It means debug &lt; trace ? Can any one confirm this please ?</p>
