In one application I've got my properties file directly in the WEB-INF
directory and I access it via:

  InputStream in = getServletContext().getResourceAsStream("WEB-INF/" + propsFile);

I see two differences between this and what you have above.  First,
you have a "/" before "WEB-INF" in your file path, and you use the
Class Loader's getResourceAsStream while I'm using the Servlet
Context's.  I'd investigate those two differences if I were you
(i.e. try the alternatives and see what happens).

Oh, just noticed another thing.  You set logFile, but you're passing
debugFile to your getResourceAsStream.  Maybe that's just a difference
you were experimenting with.  But I think the above two differences
still stand out as the significant ones.

Anyway, I see no reason you shouldn't be able to have a
WEB-INF/properties directory where you keep your properties files.
