Hi Jacques,

I recently working on this JDK-17 stuff. I just getting started work on my 
weekend for this

https://github.com/weltam/arrow/tree/graviton2/graviton2

I do this because previously I managed to port the dremio-oss to graviton2 ( 
ec2 arm processor from aws)

A couple of rough stuff from the previous experiment is in here

Feel free to check it out.

Cheers

Subject: Re: JDK-17 support?

I don't think anyone is working on this. It would be great for someone to pick 
up. I would suspect that Netty already has a cross jdk approach to this that we 
might be able to  either leverage or be inspired by.

I have wondered whether the jdk17 version should be separate for the vector 
library, based on the vector apis. It'd be great if someone evaluated the 
benefit/costs of doing such.

Are there plans to support JDK-17?  They have removed the unsafe class or at 
least most of its methods so for example I believe the 
MemoryUtil<https://github.com/apache/arrow/blob/8e43f23dcc6a9e630516228f110c48b64d13cec6/java/memory/memory-core/src/main/java/org/apache/arrow/memory/util/MemoryUtil.java>
 class cannot work the same way - as opposed to going through unsafe to convert 
between integers and nio buffers you have to go through MemoryAddress,Segment 
and friends.
