My previous comment about the threshold was wrong. Setting
the threshold in an appender to priority DEBUG will include debug messages.

The problem with your code is that you are forgetting to call activateOptions . As in:
fa.activateOptions();
Invoke activateOptions after you have set all options. This should do it. Regards, Ceki
