Use mvn dependency:tree to capture your actual classpath before and after the upgrade; this should help you identify where the clash is in your classpath. You can then use exclusions or dependencyManagement to pick up the correct version. I use IntelliJ and the "Maven Helper" plugin is invaluable for finding conflicts; I think that Eclipse has something similar built-in.
