[logback-user] Configuration initialization is too verbose

[Ceki Gulcu]

Hello Gili,

In "Chapter 3 - Configuration" [1] under the section entitled
"Automatic configuration with logback-test.xml or logback.xml", it is
stated that

  If and only if there are warnings or errors during the parsing of the
  configuration file, logback will automatically print status data on the
  console.

Since logback.xml is found multiple times on your class path, logback
is issuing a warning.

HTH,
