[logback-user] class & line conversion words not working

[Chris Cheshire]

I have just upgraded to logback 1.0 (from 0.9.x), and now the
conversion words for %class and %line just produce a question mark.

My pattern layout is

    <layout class="ch.qos.logback.classic.PatternLayout">
      <Pattern>%date [%thread] %-5level %logger %n%n Class : %class%n
Line : %line%n%n%message%n</Pattern>
    </layout>


Prior to the update this was working and now it's not. Everything else
in the layout displays as specified, except %class and %line. I do
have the java compiler generating debug information too.

Any suggestions?
