jpackage: Invalid 32-bit exe when building app-image

ADDITIONAL SYSTEM INFORMATION :
JDK 15, 16, 17 with Windows 32-bit

A DESCRIPTION OF THE PROBLEM :
The executable produced by jpackage is invalid on Windows 32-bit. It was working with JDK 14.

Moreover, it does not seem possible to build an installer on windows 32-bit. There is a hardcoded variable that force to build a 64-bit installer. See https://github.com/openjdk/jdk/blob/e3793e5a608fd44ff479734182af20a06eb0ec14/src/jdk.jpackage/windows/classes/jdk/jpackage/internal/WixPipeline.java#L115

REGRESSION : Last worked in version 14

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Build TestApp on windows 32-bit and run TestApp.exe

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Launch exe without error
ACTUAL -
Popup error dialog: GetPRocAddress ... JLI_Launch failed. System Error 127
