utPLSQL-cli NoClassDefFoundError: javax/xml/bind/DatatypeConverter

Hey, I downloaded latest distribution of utPLSQL-cli and tried to execute it on my local environment. I copied ojdbc8.jar as was written in README and even orai18n.jar from Oracle website to utPLSQL-cli/bin folder. However I am receiving the following error:
