Hopefully, the usual Java backwards compatibility will be maintained,
so mostly it won't matter.  However, the packages may be installed
side-by-side, with a symlink for the global default.  Like this example
from Fedora 13:

/usr/bin/java -->
/etc/alternatives/java -->

I can't yet comment on whether distros will choose to allow multiple
JDKs, though: just that there is no strong technical reason that
forbids it.
