File captures with the '+' character fail. When using a file spec to download, if the captured value contains a +, it will not be evaluated.
1. Set up a freestyle jenkins job
2. Add Generic-Artifactory integration and add this download spec
3. Create a repo 'paco' with the file foo/bar/TAO+ACE/foo.txt and foo/bar/TAO-ACE/foo.txt
4. Run the build and observe the failure
5. Change the download spec to replace the '+' with a '-', notice that it works as expected
NOTE: Escaping with '/' does not work
