none.
These warnings from the JESUncertaintyTool are OK and known:
(WARNING) TNamed::Multije... : analysis sample response larger than light quark jet response: setting response(sample)/r_incl = response(light quarks)/r_incl --> Check input graph responseSample in file $SFRAME_DIR/../Common/JetCPTools/files/MJESttbarSemi_rel16.root!
example code
for( JetVecIt it_jets = AllJets.begin(); it_jets != AllJets.end(); ++it_jets ) {
double uncertainty = m_jesUncertaintyTool.getUncertainty(*it_jets, AllJets, collisionVertexN, 1.);
// don't forget to correct MET!
