OS/Version: Mac OS X 10.3
Status: NEW

In running the LoggingTrial example from the book "Pro Jakarta Commons" by Oak from Apress on
MacOSX 10.3.7, java version "1.4.2_05-141.3", I get the following error:
run_example:

Up to this point everything in the book worked. I doubt user error. MacOSX java implementation?
