See https://openjdk.org/jeps/434 for JDK20 with the following changes in terms of APIs which affects our FFI implementation in Java.

This JEP proposes to incorporate refinements based on feedback, and to re-preview the API in JDK 20. 
In this version:
1. The MemorySegment and MemoryAddress abstractions are unified
     (memory addresses are now modeled by zero-length memory segments), and
2. The sealed MemoryLayout hierarchy is enhanced to facilitate usage with 
    pattern matching in switch expressions and statements ([JEP 427](https://openjdk.org/jeps/427)).

We temporarily disable the FFI specific code in JDK20 via ibmruntimes/openj9-openjdk-jdk20#12 & OpenJ9 via #16585, which we will need to update & re-enable to get this latest code work after that.

The issue will be closed very soon once the PR at adoptium/aqa-tests#4591 is merged to enable FFI test suites given everything specific FFI in JDK20 is resolved.
