Happy to see this work! This change looks fine in general. I agree that
it's good to keep this issue to remove the runtime support and separate the
`jar -i` change. JDK tools don't run with security manager enabled and no
need to wrap `System::getProperty` with `doPrivileged`.

Nit: extra line 936 can be removed.
