Can I have a look ?

@fokion Yes sure. Thanks!
May be start experimenting with main branch (1.1.x version) as a base, because it will be hard with netty5 branch (2.0.x)

Noticed that we are compiling with jdk 8 but in mac os with apple silicon I got the following error

> Failed to calculate the value of task ':reactor-netty-core:compileJava' property 'javaCompiler'.
   > Unable to download toolchain matching the requirements ({languageVersion=8, vendor=any, implementation=vendor-specific}) from 'https://api.adoptium.net/v3/binary/latest/8/ga/mac/aarch64/jdk/hotspot/normal/eclipse'.
      > Could not read 'https://api.adoptium.net/v3/binary/latest/8/ga/mac/aarch64/jdk/hotspot/normal/eclipse' as it does not exist.

So I tried migrating to JDK 17 which had its own challenges

Reactor Netty 2.0.x (which is still on milestone phases) is based on Java 17 and Netty 5, unfortunately we still don't have Netty HTTP3 ported for Netty 5

Reactor Netty 1.1.x is base on Java 8 and Netty 4 and there we have Netty HTTP3. There are no plans to move 1.1.x on Java 17.

So may be try to install Java 8 manually (for example via sdkman etc) and try again the build, it should be ok.

Ok good to know , will point my jdk back to 8 and work on this assumption. Thanks for the assistance.
