For Mailman 3, there is the REST API which can be used, and there are several Python applications that provide alternative APIs and UIs in development. It's possible that those can be run on the JVM using the Jython implementation of Python, but I don't know if Jython can be embedded in a Java application. (It is possible for Jython to call other Java libraries, though, so if you're lucky you might be able to translate your main program to Python and do most development in Java.)
Of course, the whole point to exposing a REST API is that bindings can be easily written in any language, since it's just HTTP and JSON.
One caveat though is that the core's REST API is an unauthenticated "administrative" API that should only ever be exposed on localhost. The idea is that Postorius or other equivalent would proxy the admin API through an authentication layer.
