Summary

Fixes #1141: macOS exported apps fail with JRExLoadFullError or JRELoadError.

Cause : The export logic in JavaBuild.java was only checking for directories that start with jdk-, but the embedded JDK can be named just jdk. This caused the bundling step to fail, resulting in missing JREs.

Fix : Replaced the strict .startsWith("jdk-") check with .startsWith("jdk"), allowing both jdk and jdk- prefixed folders.

Impact :

Ensures macOS exported apps bundle the JRE properly
Prevents runtime errors on macOS after export

Thanks for submitting this patch, and welcome!

Just a heads-up: we ask that contributors get assigned to an issue before opening a PR. In this case, someone else is already assigned to the issue.

I appreciate the effort you put into this. Since it's a small change, we're happy to review it and share feedback. However, we won't be merging this PR.

Just tested it on macOS (arm) and removing the dash is not enough to fix the issue
