      Making matters worse, the server is allowed to dictate any directory to the client, which means providing a blanket grant or doPrivileged on the client would be an exploitation vector and thus is not a viable solution.

      The only workaround at present is for the client to know in advance where the challenge files are stored, and pre-grant that permission to any deployment or user JAR which might perform invocations.
