This is nothing new. Compare https://bugs.eclipse.org/bugs/show_bug.cgi?id=540778 from 2018 and https://bugs.eclipse.org/bugs/show_bug.cgi?id=315619 from 2010. Seems to occur only on Windows.

Actually ed25519 is supported as of Java 15. Bouncy Castle also supports it. Unfortunately, changing the current implementation so that it would work with any of these is not possible...

Done in branch dev_3.0.0 for milestone 3.0.0-M2.

Uh... are we ready to abandon the 2.0.x stream of Apache MINA? I know for certain that Gerrit uses the MINA transport back-end with MINA 2.0.25. Jumping to 2.2.3 might...

Given that a MINA 2.2.4 is forthcoming, I think the correct way forward here would be * Leave our POM at 2.0.25. * Change https://github.com/apache/mina/blob/14d876107c60a169f11ec2c3ce3cd9aadcd9b43c/mina-core/src/main/java/org/apache/mina/core/service/IoHandler.java#L124 to a default method (empty)....

Superseded by #681. Keep the dependency at 2.0.X but also test using 2.2.X. In mina-core 2.2.5, that method will be a default method.

Sorry, this is not actionable. The description is too vague. Provide full stack traces (as text, not screenshots!), and explain how to reproduce the problem. I can only guess that...

Provide the full server log. I need to see what happened before that. Ideally you'd also have a backtrace for this exception. Maybe run your server with debug logging. What...
