[Fedora-packaging] Including a patched version of an upstream library -- advice?

[Mary Ellen Foster]

So I decided to try upping my own review karma by trying to review
some outstanding Java packages. Unfortunately, I seem to have chosen
one with an "interesting" issue:
    https://bugzilla.redhat.com/show_bug.cgi?id=464013

The package in question is "findbugs-bcel": an alternative version of
the bcel library (already in Fedora), including a fairly large patch
from the developers of the "findbugs" package. There seems to be no
hope of getting this patch into upstream bcel (e.g.,
https://mailman.cs.umd.edu/pipermail/findbugs-discuss/2007-April/001880.html).
There was a short discussion on this on fedora-devel-list last year:
http://www.redhat.com/archives/rhl-devel-list/2007-September/msg00865.html

What's the official policy here?

I guess I should try to find a more straightforward package for my
first review ...
