[logback-user] Exception logging

[Ceki Gulcu]

David,

Parameterized logging is not available for exceptions. Given that exceptions by 
definition are rare, you don't need to optimize logging for them. You just write:

logger.error("Something went wrong because " + someReason, exception);

The difference in performance is measured in terms of microseconds which is 
usually not significant in case of exceptions.

Does the above make sense?
