> When a socket path does not have the correct permissions, an error is thrown.
> That error just has the failing component of the path and not the entire path
> of the socket.
> The entire path of the socket could be printed out to allow for a direct
> check of the permissions of the entire path.
> {code}
> java.io.IOException: the path component: '/' is world-writable. Its
> permissions are 0077. Please fix this or select a different socket path.
