Paths in alternatives are not the same as package Provide:'s.

The only thing that saves alternatives paths contained in packages from 
being
erased on upgrade like the sun jre is the lack of (permitted in 
rpm-4.4.1 and later)
    Obsoletes: /path/to/alternative
in packages.

OTOH, obsoleting the shared alternative path is dain-bread packaging, 
obsolete
the specific package alternative path if you must do such things.
