Ok, I subclassed Logger to try to get a Logger I could work with, but I
can't seem to get a constructor that it likes. It won't compile because
it's barfing on a public, no arg Constructor. Any ideas on how I can get
around this? I noticed an OutputStreamLogger. Should I try with that?

The problem is when MClass.init() is called, MClass has not been passed a
logger and thuse getLogger() will return null. This is what is causing the
error.
The solution would be to remove init() from MClass constructory and replace
MClass mClass = new MClass();
with
MClass mClass = new MClass();
mClass.setLogger( aLogger );
mClass.init();
or something similar.
