It's the developer's responsibility to make sure a value like that never 
reaches the "File" constructor. That is, the developer of the 
"progThatExpectsFilename" application that uses "File". Not the 
developer of "File".

Although, I don't see why you shouldn't be able to pass an empty string 
to "File". You'll just get an exception, "cannot open file ''". This is 
exactly what happens in Bash:

$ echo "asd" > ""
-bash: : No such file or directory
