Description

When executing

FileUtils.moveToDirectory(new File('foobarbaz'), new File('/tmp'), false)

while "foobarbaz" doesn't exist, I get

java.io.FileNotFoundException: Source 'foobarbaz' does not exist 

but the documentation doesn't mention "FileNotFoundException".

OTOH, if "foobarbaz" exists both as source and in the destination directory, I get

org.apache.commons.io.FileExistsException: File element in parameter 'null' already exists: '/tmp/foobarbaz'

What's that "parameter 'null'"?
