them with your classes you would do:

so they don't overlap and see if the problem goes away.  If it does then it is a bug in Log4j.

on my Mac.  I found a project I had used before that had two classes and modified it slightly
for this test.  I ran the test and got the following output (which will probably look terrible
after it is emailed).   The log4j2.xml file was in the classes directory of my project so
it could be found in the

list accepts attachments.  I also got an output file which should be in the "target" directory
in the zip.
