already on micronaut 2.x (2.5.5) 😄

[timtebeek]

Apologies! I was mistakenly looking at the plugin version, which is still at 1.5.2 🙈
In any case the plugin has seen a few upgrades as well (2.0.6) being the latest,
and the Micronaut 3.0.3 upgrade comments still stand. 🙃 Luckily OpenRewrite makes it easy.

I try on another project, the change will take some time, even more if we decided to remove the RxJava2 deps.
OpenRewrite will not handle special case on internal bean from micronaut.

Are you willing to do that ?

[timtebeek]

I could look into it, but not that at home in Micronaut yet. Could be a nice challenge, could fail miserably. ;)
If nothing comes of my attempts anyone else is welcome to try as well!

Micronaut 3.0.2 should resolve the folllowing high cves CVE-2021-37137, CVE-2021-37136 from io.netty package, will make an attempt to rebuild.

@RoachMJ have you been able to upgrade to 3.0.2? I am facing the same issue as the CVEs you mentioned above. Is there a way I can make local changes and do a gradle build?

[gquintana]

I am particularly interested in this change micronaut-projects/micronaut-security#720 which is available in micronaut-security 3.0.0-RC1

The upgrade to micronaut 3.2 is done on dev branch from this bf8c68e.

I will appreciate some test since there is a lots of changes, especially on the auth side that was breaking compatibility on micronaut 3.

I planned to release a new version next week.

Thanks

Hello, @tchiotludo
I deployed dev branch on some instances and I experience the behavior documented in #907.

Other than that, everything seems ok.
