Pass '-n' flag to native unzip command so that it will never overwrite existing files.  This can happen, as in the case of a bouncy castle zip, where the zip file actually contains two copies of exactly the same file.  Without this flag, the shelled out unzip command will just stop and wait forever for someone to tell it what to do about the conflict.
