Gary D. Gregory commented on IO-877:
------------------------------------
Hello [~epluribusunum]
If you try {{new File("").listFiles()}} you get a null, meaning that {{new
File("")}} doesn't mean the current directory.
Use {{new File(".")}} for the current directory.
Using {{new File("")}} might have worked in the past just by luck of us using
some different internal logic.
