Added by Michael Kay about 1 year ago
We're doing
directories.push(Arrays.asList(nextFile.listFiles(filter)).iterator());
and it seems that nextFile.listFiles(filter) is returning null.
The Javadoc for listFiles says "Returns null if this abstract pathname does not denote a directory, or if an I/O error occurs."
We know it's a directory, so I guess the only explanation is that an I/O error occurred. Odd that this should return null rather than throwing an exception. But I guess we should check for null here rather than throwing an NPE.
