Automatically generate native-image conditional metadata for ChannelHandler implementations. by gradinac · Pull Request #12794 · netty/netty

gradinac · 2022-09-11T01:02:40Z

Motivation:
Analogous to #12738, this PR introduces automatic conditional native-image metadata generation for different ChannelHandler implementations

Modification:
This PR is basically the same as #12738, but adapted to conform to the Java language level 6.
This PR also adds the metadata generation to more subprojects that contain ChannelHandler implementations.

Result:

Fixes #12725

@chrisvest Thank you for looking into this :)
The failure seems to be caused by forcing runtime initialization of the BrotliDecoder in the codec-http subproject instead of the codec project where this decoder is located - I've pushed a fix to the PR and I'll check if it passes

chrisvest · 2022-09-26T23:38:04Z

Thanks!

gradinac · 2022-09-27T09:19:58Z

Thank you very much for merging this! :) Sorry for not looking into this PR further earlier, I think it was stuck on some transient issue - I had rebased it and re-run the workflows and they've passed
