A good question!

If java.io.File f exists, then f.getCanonicalFile().toPath() should be 
equal to f.toPath().toRealPath(true). I say "should" because it isn't 
guaranteed and you will find cases where it won't hold. For example File 
doesn't work with sym links on Windows (yet), or it doesn't preserve the 
platform representation of the file path.
