Exported project to Windows cannot find Java

[alekratz]

Description

I am exporting a project on Linux, and creating an .exe for Windows. When I try to run the .exe on a Windows 10 machine, I am given this error: "This application requires a Java Runtime Environment 17". However, I have already installed JRE 17, the JAVA_HOME environment variable is set correctly, and the PATH environment variable is set up to point to the correct version of Java.

Expected Behavior

Application starts up and runs as expected.

Current Behavior

Error message described above. When I run java -version it shows the expected version.

Steps to Reproduce

1. Export to Windows via Linux
2. Install JRE 17
3. Set JAVA_HOME and PATH environment variables appropriately
4. Try to run application.

Your Environment

• Processing version: 4, rev 1291
• Operating System and OS version: Arch Linux
• Other information: Exporting to Windows target, running on Windows 10

Possible Causes / Solutions

I can skim the source code to see what may be going on, I haven't taken the time to do that.

Additionally, I'm using a couple of weird built-in Java libraries, like the clipboard and gzip. I don't expect that using those would be causing this issue however.

Java 8 is also installed on this machine, but I don't think any environment variables are pointing to it.

It's probably the Java 8 on your machine inserting itself somehow… Try copying the JRE to a folder called java adjacent to that .exe. (So that java/bin contains java.exe and that sort of thing.) Does that work?

Found the problem here while looking into something else. Fixed for 4.2, when released. Thanks for the report…

Hey, thanks so much for checking this out (and fixing it, nice). I was going to give your suggestion a try when I had Windows access again. Keep up the awesome work.
