[logback-user] Problem with configuring logback programatically

[Ceki Gülcü]

The appender.setLayout(patternLayout); call generates a warning. 
However, at that time the appender does not know its context.

Change
  appender.setLayout(patternLayout);
  appender.setContext(lc);
to
  appender.setContext(lc);
  appender.setLayout(patternLayout);

In which case you will get the warning message:

|-WARN - This appender no longer admits a layout as a sub-component, set 
an encoder instead.
|-WARN - To ensure compatibility, wrapping your layout in 
LayoutWrappingEncoder.
|-WARN - See also 
http://logback.qos.ch/codes.html#layoutInsteadOfEncoder for details

Visit  http://logback.qos.ch/codes.html#layoutInsteadOfEncoder for 
further instructions.
