More user friendly fail message (was NullPointerException) (#9665)

Yes, I should never have created "D:\eclipse workspaces" in the first
place.
No, I am not replacing "%20" with spaces, or creating an URI instance.
"D:\eclipse%20workspaces" is a valid folder and I'm not willing to go
down the rabbit hole and see what that turns into.
