Sebb commented on IO-157:
-------------------------
Binary compatibility relies on the API signature, which includes the return
type, but does not include the throws clause.
So you can have a binary compatible jar which is not source-compatible, and
vice-versa.
> [FileUtils] Return target File from copyFileToDirectory()

> It would be useful if the FileUtils.copyFileToDirectory() method returned the
> target file to which it does the copy. Currently, it creates the target File
> object, passes it to copyFile(), and discards the reference. This could just
> be returned from the method instead.
