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

They are on epel7 and fc23 and newer.

The package names are rxjava, archaius-core, hystrix-metrics-event-stream and hystrix-core, exactly like the jar name.

For epel7 it will definitely work, on fedora we have to try it out.

There might be a dependency to google guava on the newer archaius. Newest and very old archaius versions don't have this guava dependency.

At least everything except archaius-core can be taken from fedoa too.

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.
