Logger interface and Log4j implementation is in util.jar of Enhydra 5.1 (not in enhydra.jar).

In Enhydra 5.0 Logger interface and only Standard implementation was in core.jar. In Enhydra 5.1, Logger (with two implementations - Standard and Log4j) is in util.jar. That?s a difference.

Jonas uses Monolog for logging - Enhydra uses its own Logger.

For 'future' Enhydra 6.0 we made Enhydra Logger implementation for Monolog and on that way we use the same logger for Jonas and Enhydra Application Framework and Enhydra applications. And it works.
