I'm working on a JavaFX application that requires JDK 17+, which only supports 64-bit operating systems. I'm using the launch4j-maven-pluginto create an EXE file, and I need to ensure that when users click the EXE, it checks if they're running a 64-bit OS before attempting to launch the JVM.
The challenge is that this detection logic cannot be written in Java code since JDK 17 won't run at all on 32-bit systems. I need a way to implement this check at the native wrapper level before the JVM even starts.
What approaches are available with launch4j to:
Detect the operating system architecture (32-bit vs 64-bit) at the native level Show a custom error message if the system is 32-bit Prevent the JVM from attempting to start on incompatible systems
