Hi all,
Please review this small change to the List interface that specifies that
unmodifiable lists (returned by List.of et al) implement the RandomAccess marker
interface. In fact, they already do; the intent of this section was to specify
the user-visible characteristics of such lists, but this particular
characteristic was accidentally omitted.

Patch below. I'll follow up with a CSR request.
Thanks,
