I don't see a AnnotationRegistry::registerFile in the app/autoload.php that
ships with the Symfony 2.1 standard distribution (as of
67cbb5771f38ca1ab71c83916d2fedb3c0311b16).

Thanks. I'm a bit behind on this, but do you suppose it makes sense to advise:

use Doctrine\ODM\MongoDB\Mapping\Driver\AnnotationDriver;

AnnotationDriver::registerAnnotationClasses();

...over the more verbose AnnotationRegistry::registerFile(...) method we currently suggest (for ODM annotations). This is what we've been using in the test suite's bootstrap for some time.

Edit: It's also used in this bundle's 2.0 branch as well.

@jmikola sure, that looks cleaner. I like that it allows you to not have to specify a file path.

I've not used it before, but I just tried it locally and it seems to work fine.
