jython has been basically unmaintained for quite some time
replyWell, they never made the jump to Python 3. But shipping 2.7 interpreters in 2024 was quite an achievement on its own. So their users already know this pain. And from my experience in academia, python 2.7 and java 8 will probably be used for another 20 years before the last machine running that stuff burns out.
replyGraal vm has support for python 3 unfortunately it’s funded by oracle.
replyIf it makes you feel any better (it probably doesn't), the development of OpenJDK and the Java language itself is also mostly funded by Oracle
replyJava is funded by Oracle, all of it.
replyPeople parrot to use OpenJDK without understanding it is mostly Oracle employees working on it.
And if you dislike Oracle, the other minor contributors are Red-Hat, IBM, SAP, Microsoft, Alibaba, Azul,... which for many HNers are the same.
Jython is unmaintained, I'd recommend Clojure. Use python libraries and code while seamlessly targeting the JVM.
replyjpype and graalpy are life.
replyjython went EOL.with python 2 going EOL.
