Mark Bryan Yu updated IO-141:
-----------------------------
Attachment: Fix_recursion_bug.patch
Patch to fix the recursion bug.
This patch will check the absolute path of the destination directory and the
absolute path of the File objects from listFiles(). If they are equal, then
don't copy the destination directory and continue the iteration
> [IO][PATCH] Infinite loop on FileUtils.copyDirectory when the destination
> directory is within the source directory

>
> When you attempt to copy a directory and the destination directory is inside
> the source directory an inifinite loop occurs in the copyDirectory causing
> Commons-IO to create a folder w/o stopping until its reaches OS limitation.
> This code will recreate the bug:
> FileUtils.copyDirectory(new File("C:\\temp\\test-io\\a\\."), new
> File("C:\\temp\\test-io\\a\\." + File.separator + new Date().getTime()));
