[logback-user] Resource [file:logback.xml] occurs multiple times on the classpath

[Jason Berk]

new user here....making the jump for log4j to logback.  Running an
executable jar where logback.xml is NOT in the jar.  Application works
as expected, but I'm seeing all these "Resource [file:logback.xml]
occurs at [file:logback.xml]" in the log.

-Dinput.file=test.txt -Doutput.dir=pdf -jar MyJar.jar mortgage

....my app logs omitted.....

here is my logback.xml:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <encoder>
      <pattern>%d %-5level %C[%M%L] - %msg%n</pattern>
    </encoder>
  </appender>

  <!-- Turn off third party chatter -->
  <logger name="org.springframework" level="OFF"/>
  <logger name="org.apache" level="OFF"/>

  <root level="debug">
    <appender-ref ref="STDOUT"/>
  </root>
</configuration>

1) why is this happening?
2) is this something I am doing wrong (and how to fix)

thanks for the great tool and any help.
