Having talked with @benedikt-voelkel about it, it is apparently due to a change to the test/run_generator_tests.sh script that was not propagated (the o2-sim command at line 88 is missing the option --configKeyValues "GeneratorPythia8.includePartonEvent=true). With the change, the test of GeneratorHFJETrigger_ccbar.ini is successful on my machine.

#1318 will solve the problem
Once merged, simply rebase your devs and push again

@aimeric-landou you can now rebase and push again
