ListFile processor "Path filter" not applied against base directory

ListFile processor "path filter" is applied against sub directories only and not the base directory.

Consider scenario where you want to only list files found in subdirectories with directory name "data" and you have directory tree structure as follows:

/input/basedir/<timestamp>/data

So you configure the listFile with "Input Directory" of "/input/basedir" and a "Path Filter" with ".*?/data" with the expectation that only files found in the various sub "data" directories are returned.

observed behavior is that listFile will return all files found in the base directory "/input/basedir" as well as all file from subdirectories matching the "Path Filter".
