Describe GraalVM and your environment :

  • GraalVM version or commit id if built from source: [Oracle GraalVM 22.0.1+8.1 (build 22.0.1+8-jvmci-b01)]
  • CE or EE: [CE]
  • JDK version: [21]
  • OS and OS Version: [Debian12.5]
  • Architecture: [amd64]
  • The output of java -Xinternalversion:
 Java HotSpot(TM) 64-Bit Server VM (22.0.1+8-jvmci-b01) for linux-amd64 JRE (22.0.1+8-jvmci-b01), built on 2024-03-14T00:30:39Z by "buildslave" with gcc 13.2.0

Describe the issue
I have a simple swing program that uses native-image to generate an executable file. I found that something went wrong when it was run. The error message was "Caused by: java.lang.RuntimeException: Fontconfig head is null, check your fonts or fonts configuration"

Code snippet or code repository that reproduces the issue

package org.example;
import java.awt.*;
import javax.swing.*;
public class SwingSample {
    public static void main(String[] args) throws Exception {
        if (System.getProperty("rrr","").equals("")) {
            System.setProperty("java.home",".");
        }
        SwingUtilities.invokeAndWait(() -> {
            JFrame frame = new JFrame("Hello World");
            JButton button = new JButton("Hello");
            button.addActionListener(e -> {
                System.out.printf("Hello, World!%n");
            });
            JPanel panel = new JPanel(new FlowLayout());
            panel.add(button);
            frame.add(panel);
            frame.setSize(400, 300);
            frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            frame.setVisible(true);
        });
    }
}

Steps to reproduce the issue

  1. mvn clean package
  2. java -Drrr=123 -agentlib:native-image-agent=config-output-dir=./cdir -jar jdk21graalvm-1.0-SNAPSHOT.jar
  3. native-image -jar jdk21graalvm-1.0-SNAPSHOT.jar -H:+ReportExceptionStackTraces --no-fallback --link-at-build-time -H:ConfigurationFileDirectories=./cdir -H:+AddAllCharsets --report-unsupported-elements-at-runtime --enable-url-protocols=https,http

After the build is completed, the following exception occurs when executing it

Hey @selhagani . Okay, I'll just paste them out, just two files.

SwingSample.java

public class SwingSample {
    public static void main(String[] args) throws Exception {
        if (System.getProperty("rrr","").equals("")) {
            System.setProperty("java.home",".");
        }
        System.getProperties().list(System.out);
        SwingUtilities.invokeAndWait(() -> {
            JFrame frame = new JFrame("Hello World");
            JButton button = new JButton("Hello");
            button.addActionListener(e -> {
                System.out.printf("Hello, World!%n");
            });
            JPanel panel = new JPanel(new FlowLayout());
            panel.add(button);
            frame.add(panel);
            frame.setSize(400, 300);
            frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            frame.setVisible(true);
        });
    }
}

Hi @zgmgt, I wanted to share a helpful update regarding the issue you're facing.
When I used the latest version of GraalVM CE which can be found here and I removed this part from the code:
if (System.getProperty("rrr","").equals("")) { System.setProperty("java.home","."); }
Then I ran the command
mvn clean package
Followed up by
java -agentlib:native-image-agent=config-output-dir=./cdir -jar jdk21graalvm-1.0-SNAPSHOT.jar
then I used this command to generate the native image:
native-image -jar jdk21graalvm-1.0-SNAPSHOT.jar -H:+ReportExceptionStackTraces --no-fallback --link-at-build-time -H:ConfigurationFileDirectories=./cdir -H:+AddAllCharsets --report-unsupported-elements-at-runtime --enable-url-protocols=https,http -Djava.awt.headless=false
and then I ran the native image using the following command
./jdk21graalvm-1.0-SNAPSHOT -Djava.home=/home/soufiane/Downloads/graalvm-community-openjdk-22.0.1+8.1

Then it worked correctly.

The issue is attributed to how some AWT/Swing classes are loading required properties from the JVM at runtime by invoking the system.getProperty("java.home") which is not available to native images at runtime.
