Derek Mahar commented on LBCLASSIC-159:
---------------------------------------

Please note that this is a production issue for me since our production environment disallows applications to write messages to standard output.  Since this duplicate classpath entry message causes Logback to write warning and informational messages to standard output, this may prevent us from releasing our application into production.

> I receive strange warnings in the status info. It says that logback.xml, which in this case comes from a file and not from the classpath, occurs multiple times. The file is specifies and logged using absolute path, so even relative paths cannot cause the warning.
> Logback configuration file is specified by the system property "logback.configurationFile". It is done by the Resin application server, somehow it is able to supply different properties for different web applications. I don't think this is important, however. Maybe I am doing something wrong, but at least the message doesn't help.
