The mockserver uses the apache commons lang3 lib in version 3.12.0 I am trying to use another lib, that use some dependency which transitively uses the apache commons lang3 lib as well, but in version 3.17.0 As we are using maven, it takes the version 3.12.0 of the lang3 lib as it has a lower nesting in the dependency tree... As the other lib i try to use needs a feature of the 3.14.0+ version of the commons lang3 lib, i get errors when executing my project. Would be nice, if you could release a new bugfix/minor version with the newest lang3 lib version (3.17.0) Thanks!
