Dongjoon Hyun updated SPARK-53225:
----------------------------------
Description:
It's tricky because we need Java 17 and Java 21 distribution separately.
bq. This release leverages the new Java Foreign Function & Memory (FFM) API
capability ([JEP 412](https://openjdk.org/jeps/412)), which is in incubation in
Java 17. This means that Java 17 is required to compile this code and at
runtime. The location of the FFM code was moved from jdk.incubator.foreign in
Java 17 to its position for preview in Java 21 at java.base/java.lang.foreign.
As a result, code compiled with Java 17 FFM will not run with Java 21, the next
LTS. Java does not provide backward compatibility for older incubation code.
