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 incur a lot of testing work.

[tomaswolf]

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). That would re-instate binary compatibility, right?
• Leave our code unchanged. (I.e., don't add the new override.)
• Mention in the documentation of sshd-mina that it works with MINA >= 2.0.25 or MINA >= 2.2.4.

[gnodet]

We can't add the method as it has a FilterEvent parameter, which is a new class introduced in Mina 2.1.0.
I don't think there's a way to support both 2.0.x and 2.1.x at the same time.
@elecharny any thoughts ?

[tomaswolf]

@gnodet: yes, I know. But if Apache MINA makes it a default method, then we don't have to declare it at all, and thus we can at least support 2.0.x and >= 2.2.4 with the same code. Yes, we cannot support 2.0.x and (2.1.x or <=2.2.3) at the same time.

[dependabot]

A newer version of org.apache.mina:mina-core exists, but since this PR has been edited by someone other than Dependabot I haven't updated it. You'll get a PR for the updated version as normal once this PR is merged.

See apache/mina#48.

[tomaswolf]

Superseded by #681.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.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
