Have you tested it on windows, for example, signing in as admin, and the
file which is set read only is still writable?:)
It is always good to follow RI or else we might encounter odd problems in
real applications.
Furthermore, "root" is the concept of OS, so I do not think the role should
be treated specially in the layer of java. We can delegate it to OS service
naturally if possible. I guess RI uses another implementation, for example,
the system call which itself deals with the user account.

Hi Tony:
No, setReadOnly is used to change the access privilege. After this
change harmony and RI behaves differently.
