NullPointerException on ResourceWatcherService

[gregoryb]

I made a mistake while i deployed a script. I created a file (instead of a directory) named "scripts" to save my script. And now, even if scripts is a directory (with the script inside), i got the following exception

I'm not able to reproduce this. I added a test, which passes on 1.x and the 1.2.1 release. Can you list of set of reproducible steps?
