See the tracker bug. if [[ -n ${REPLACING_VERSIONS} ]] && ! version_is_at_least 7.2.4.3 ${REPLACING_VERSIONS} ]]; then This will fail if RV has >1 value.
In this particular case, I think it would only be a single value becayse ant-core would never be slotted. We'll remove that message on the next bump (which is overdue) anyway because 1.7 was forever ago.
This disappeared a while back.
