4.1 config file path migration question

I have hopefully a quick question on how Cayenne can be configured to 
use a configuration file outside of a JAR/WAR.

I currently use this to reference an absolute file path for my Cayenne 
files but I see that FilesystemResourceLocator is now deprecated ...

             Module myModule = (org.apache.cayenne.di.Binder binder) -> {
                 binder.bind(ResourceLocator.class).toInstance(new 
FilesystemResourceLocator(filePathForCayenne));
                 ...

What is the "new" way to replicate the same functionality.  The 
deprecated notes just provide the same example I'm already using.

Thanks,

Andrew
