Currently the build process of the engine disables repacking of .jar files only for quick builds, intended for tests. It does so setting the "__jar_repack" global macro to 0:
%global __jar_repack 0
But this repackaging isn't really useful for us, as repackging is intended for packages that contain multilib .jar files, as described here:
https://www.redhat.com/archives/fedora-devel-java-list/2008-September/msg00041.html
As repackaging takes a long time, it would be better for us to always disable it, as already done upstream in the master branch:
packaging: Never repack .jar files

Moving to 3.6.5 for verification as we won't have time to verify it for 3.6.4
