> I work with a directory that contains :
> - a file test.csv (my data for recommendation)
> - a directory test (for other purpose ...)
> And surprinsigly i encountered the following
> error.java.io.FileNotFoundException: .../test (Is a directory)
> at java.io.FileInputStream.open(Native Method) ~[na:1.7.0_03]
> at java.io.FileInputStream.<init>(FileInputStream.java:138)

> After looking at the code, i saw that the method findUpdateFilesAfter doesn't
> filter directories.
> I proposed to add a test in the method :
> ...
> for (File updateFile : parentDir.listFiles()) {
> + if (!updateFile.isDirectory()) {
> String updateFileName = updateFile.getName();
