It's just a warning in your logs, isn't it? So then it doesn't
interrupt anything.

But indeed, choosing system property "user.dir" as the default
template directory is a unfortunate legacy, that haven't noticed until
now (thanks). By default the Configuration should use some kind of
dummy TemplateLoader that just says "not found" for everything. It
would be easy to implement that, only, it's not 100% backward
compatible, so it should only appear in 2.4. (Unless, you say it's an
urgent mater, in which case it's always possible to introduce a static
method and/or system property to control this.)
