Sebb commented on JCI-68:
-------------------------
The problem is the line:
final File[] childs = file.listFiles();
This can be null, e.g. of the file does not denote a directory, or some IOError
(which presumably includes protection issues)
It would be easy to detect this and return an empty array.
Should the problem be logged?
