Yes I'm aware of this bit strange thing.
Maybe only sm.checkRead(USER_DEPLOYMENT_FILE.getFullPath()) schould be checked?

I did not tested that, but accoding tojavadoc (and code) not existing file is ok, as it  do nothing with file itself or its existence, but with  RuntimePermission("readFileDescriptor").
