It's certainly better just encapsulating whatever TemplateLoader you
got from where you got it still now (like maybe from
cfg.getTempalteLoader), and blindly forward the method calls to it in
MyTemplateLoader, except that you fiddle with the Reader of course.
That way you don't assume that the encapsulated one is
FileTemplateLoader, only that it's a TemplateLoader. It's cleaner and
more flexible then. Like if you later decide to load templates from
other sources than the file system, it will still work.

(That's not the fastest way due to the buffering, but in most apps it
doesn't mater.)
