You can check if there is a project like that in the incubator, or suggest one if you have an idea or some code to donate. Most new projects are related to existing ASF projects, or use ASF libraries, or are created by someone already in the ASF that maybe use/prefer Java. But there is no requirement on a project being Java. See Airflow, Arrow, Log4net, httpd... it's just a question of people creating the proposals that must show a possible community of users/devs to use/support it.
