Probably not the best example. A piece of data (a media file in your
example) has so many different kinds of applications associated with it,
some might even be on different systems and the data is exported via a
number of means (http, nfs, etc.) Java bytecode, unless they're applets,
are much easier to predict requirements for. There is a huge probability
that they will need a JVM, and unlike media players, from outside,
they're designed to function in the same way.

As examples go, it's closer to say that JVMs are to Java applications or
even just bytecode what glibc is to native applications.

In Fedora, openoffice.org-core-2.2.0 Requires the virtual package java.

You CAN have the app before the JVM, I suppose, the same way you can
"rpm --nodeps -ivh openoffice.org-core.2.2.0....", but they'd just be
bytes taking up space in your filesystem.

Honestly, I tried to answer here
(https://www.redhat.com/archives/fedora-devel-list/2007-September/msg00396.html), here (https://www.redhat.com/archives/fedora-devel-list/2007-September/msg00414.html) and here (https://www.redhat.com/archives/fedora-devel-list/2007-September/msg00490.html), but I guess I'm misunderstanding the question.
