Project mention: Stepping down as Mockito maintainer after 10 years | news.ycombinator.com | 2025-12-28
> Is there a point at which library maintainer feedback would meaningfully influence a by-default JVM change?
Of course, just keep in mind that all these changes were and are being done in response to feedback from others. When you have such a large ecosystem, users can have contradictory demands and sometimes it's impossible to satisfy everyone simultaneously. In those cases, we try to choose whatever we think will do the most good and the least harm over the entire ecosystem.
> JPMS is a good example: --add-opens still remains valuable today for important infra like Hadoop, Spark, and Netty. If other, even more core projects (e.g. Arrow) hadn't modernized, the exceptions would be even more prolific.
I think you have answered yourself. Make sure the libraries you rely on are well maintained, and if not - support them financially. BTW, I think that Netty is also abandoning its hacking of internals.
> If libraries so heavily depended upon like Mockito are unable to offer a viable alternative in response to JEP 451
But they have, and we advised them on how: https://github.com/mockito/mockito/issues/3037
The main "ergonomic" issue was lack of help from build tools like Gradle/Maven.
