I think these ^ are all related to the use of Hystrix, Roman will know.

Avalon framework, Batik, xmlgraphics and FOP can't be replaced by links,
because the versions included in Fedora are newer than what we need, and
they don't work correctly for us.

This ^ is an oVirt project, but not distributed as RPM, only via Maven
Central, so it can't be replaced with a link.

These ^ are part of the engine, they should go in
/usr/share/java/ovirt-engine, and should be replaced by links.

The version of the spring framework in Fedora (3.2) is older than the
one we need (4.2), so those can't be replaced by links.
