Subject Re: Two classes, logging to the same file...
Date Tue, 23 Oct 2012 17:59:31 GMT
That is good to know. However, your test has spawned a suspicion that the problem may be related
to one class starting with the name of the other.  Try renaming Comtor or ComtorStandAlone
so they don't overlap and see if the problem goes away.  If it does then it is a bug in Log4j.

I'll try modifying my test to emulate that and see if I get the problem.

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 classpath.  I will attempt to add the project zip to the email but
I don't know if this list accepts attachments.  I also got an output file which should be
in the "target" directory in the zip.
