Gradle jpackage creating unrunnable application

I am trying to run jpackage with a bare bones Gradle JavaFX application mostly to try things out. There is nothing special about it, its the IntelliJ JavaFX sample with Gradle added in. The application runs fine with gradlew clean build run. However, when creating a package with gradlew jpackage the resulting exe crashes instantly and creates an hs_err_pid.

# A fatal error has been detected by the Java Runtime Environment:
#
#  EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x0000000000000000, pid=1132, tid=15340

I've tried the answers on a similar question but they did not work.

• Copying zip.dll from {app}\runtime\bin to {app}\
• Trying other JDKs
  • AdoptOpenJDK 11
  • AdoptOpenJDK 14
  • AdoptOpenJDK 15
  • BellSoft Liberica JDK 15

build.gradle looks like this

// Setup Gradle
plugins {
    id "application"
    id "org.beryx.runtime" version "1.12.2"
    id "org.openjfx.javafxplugin" version '0.0.9'
}

repositories {
    mavenCentral()
    jcenter()
}

// Setup application, dependencies
group = "io.mattw.sample"
sourceCompatibility = 15
targetCompatibility = 15

application {
    mainClassName = "io.mattw.sample.Main"
}

javafx {
    version = 15
    modules = ["javafx.base", "javafx.controls", "javafx.fxml"]
}

dependencies {

}

// Setup release
// https://simply-how.com/custom-java-runtime
runtime {
    addOptions("--strip-debug", "--compress", "2", "--no-header-files", "--no-man-pages")
}

tasks.runtime.doLast {
    copy {
        from("src/main/resources")
        into("$buildDir/image/bin")
    }
}

Edit:

When running the exe with WinDbg (preview), I get the following output. Possibly relevant that I have Java 8 installed normally though I'd expect it to use the bundled SDK and not the systems.

With Liberica I'm able to make it work by adding the following line:

runtime {
    addOptions("--strip-debug", "--compress", "2", "--no-header-files", "--no-man-pages")
    addModules("javafx.base", "javafx.controls", "javafx.fxml") // <----
}

Without that, it seems like the javafx.controls module is not added to the generated runtime image (you can check that with runtime\bin\java.exe --list-modules).

Running the application manually, as well as through the generated exe works after that.

Without Liberica, I was able to get some more information by adding the --win-console option to jpackage as follows:

runtime {
    addOptions("--strip-debug", "--compress", "2", "--no-header-files", "--no-man-pages")

    jpackage {
        imageOptions = ["--win-console"] // <---
    }
}

Running the generated exe results in

Error: JavaFX runtime components are missing, and are required to run this application

Which I believe is a problem with the javafx modules not being put on the module path, but on the class path (which AFAIK is not supported nowadays). That seems to be a problem with the runtime plugin being used (which says it does not support modular applications).

I was able to manually make it work by adding

runtime {
    ...
    launcher {
        jvmArgs = ["--add-modules=javafx.base,javafx.controls,javafx.fxml"]
    }
}

And then manually copying the javafx jars to the app\mods folder (which I had to create). Looking at the generated {app}.cfg file jpackage creates that's what the launcher will use as module path. I also deleted the unneeded app.classpath entries for the javafx jars from the {app}.cfg file.
