The Vector API does not compile with --release 16 Was: Vector API support in JDK 17-ea

[Remi Forax]

If it interests someone, I was able to reproduce the issue with a jdk that I build myself,
the issue arise when I any version of the jdk-17 but I tries to compile with --release 16 (using Maven)

Using --release 17 solves the issue.

So it's not related to the Azul JDK at all.

cheers,
Rémi
