I'm trying to install an x86 JDK in a GitHub action, and I found out that the specified architecture is ignored in this script. By looking at the code, I saw that arch is not used when the script is determining which archive to download. See

On Windows, it will always download the archive ending with -win_x64, while it should actually download the archive ending with -win_i686.zip when the architecture is x86. The issue also seems to be present for other OSes (although I never tried them)

Be aware that Zulu doesn't seem to provide x86 Windows binaries for all Java versions.
