  When creating a FileDataSource from on a symbolic link to a folder, it's impossible to list the files in that folder. Creating a FileDataSource to the target folder works properly.

• If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem
  Create a symbolic link to a folder that is not empty
  Create a FileDataSource from the symbolic link
  Call the listNames method: the return set is empty.

• What is the expected behavior?
  It should list the files in the target folder

• What is the motivation / use case for changing the behavior?
