can you create a test for this based on a subclass of HttpCompressionTestBase like other compression schemes have ?

@sullis test is not passing, can you investigate ?

I believe we need to wait for Netty 4.1.109. The Netty team recently updated HttpContentDecompressor, and the change will be included in the 4.1.109 release.

I am going to convert this PR to "draft" for now.

in my local workspace, I upgraded to a Netty snapshot release ( Netty 4.1.109.Final-SNAPSHOT).

Http1xZstdCompressionTest passes with the Netty snapshot.

ok then it's in standby for now

@sullis can you update the PR since now vertx depends on Netty 4.1.109.Final ?

Awesome! I just pushed an update. Let's wait for the CI build to finish 😎
