Log4j gives user and developers great control over how much shows up in logs with hierarchical loggers, levels and markers. If a library chooses to use a single logger with a single level, well, that's silly. But at least you can turn OFF that logger! Unless the library uses the root logger... and that would be REALLY silly.
