Bug 1151442

I have a bunch of trips for the rest of the month so would not be able to look into it before November. Let me know if you want to fix it yourself, request commit rights in pkgdb and I'll approve it, otherwise you would have to wait few weeks.

Once I submit the bug, and see who is maintainer, I realized my error in bugging it :))

Is one line post-build jar modification ok for you? If so, I will fix it for you in asap.

Just to be clear
to the end of the build, 
jar -umf X  %{jacoco_dir}/org.jacoco.agent.rt.jar 

where X is file with three lines:
Manifest-Version: 1.0
Premain-Class: org.jacoco.agent.rt.internal.PreMai

EOF

*Premain-Class: org.jacoco.agent.rt.internal.PreMain

Not ideal fix but feel free to do it that way together with TODO comment to inspect why it's not done by the build.

Here we go: https://jvanek.fedorapeople.org/jacoco-premain/
I have asked for push access. If you grant, I will build and push updates. Otherwise feel free to act:
