re: "/attachments" appending to your path:
if (!filesystemPath.contains("${")) {
filesystemPath = filesystemPath + "/attachments/${hash}/${pk}${ext}";

if you don't specify any variables in your path, it appends them for you ... if
you were to set your filesystem path to
"/tmp/erattachments/${hash}/${pk}${ext}, it wouldn't.
