getClusterP4()

TLorentzVector HIJetRec::getClusterP4 ( const xAOD::CaloCluster * cl, xAOD::CaloCluster::State s )

: getClusterP4 Added during Rel22 migration.

We should never use CaloCluster_v1::p4() because this four vector can never have a negative energy. Therefore, if one tries to use setClusterP4 and then retrieve the cluster four momenta, must use this new method that keeps the cluster information as set in setClusterP4 (negative E and flipped eta phi)
