[logback-user] Try to use an evaluator JaninoEventEvaluator in logback. But does not work to filter out depending on condition

[Ceki Gulcu]

Hello Skasish,

Please install OnConsoleStatusListener which should give clues as to the 
underlying causes of the problem.

See http://logback.qos.ch/manual/configuration.html#statusListener for 
details.

I suspect that the expression given to JaninoEventEvaluator is invalid 
as lacks return statement for the implicit 'else'. Logback's internal 
status messages (enabled with OnConsoleStatusListener) are your friend.

HTH,
