[native-image], GraphicsEnvironment getAllFonts with --initialize-at-build-time= results in linker errors / Unsatisfied links

[Karm]

Describe the issue
The following code, Main.java:

import java.awt.Font;
import java.awt.GraphicsEnvironment;

public class Main {
    public static void main(String[] args) {
        for (Font font : GraphicsEnvironment.getLocalGraphicsEnvironment().getAllFonts()) {
            System.out.printf("%s, %s\n", font.getFontName(), font.getFamily());
        }
    }
}

compiled as:

export JAVA_HOME=/home/karm/tmp/graal-labsjava11-build;export GRAALVM_HOME=${JAVA_HOME};export PATH=${JAVA_HOME}/bin:${PATH}
javac Main.java
java -agentlib:native-image-agent=config-output-dir=./META-INF/native-image Main
native-image --no-fallback --initialize-at-build-time= -H:DeadlockWatchdogInterval=2 --native-image-info --verbose Main

produces either an occasional deadlock on my system, see deadlock log or it crashes later during the build on undefined reference to `Java_sun_font_Freetype*, see log.

Describe GraalVM and your environment:

• GraalVM version master 40b6448, 21.1 CE
• JDK major version: 11
• Labs JDK: labsjdk-ce-11.0.11-jvmci-21.2-b01-debug
• OS: Centos 8
• Architecture: AMD64
• gcc 8.3.1 redhat
• relevant system libs: freetype-2.9.1, harfbuzz-1.7.5, fontconfig-2.13.1

See also the discussion on #3417 for more details.

Summary: Initializing all classes at image build time for AWT/Swing is not feasible at this time. It would require quite extensive patching of the JDK code, which cannot be done in a maintainable way using substitutions. The only proper way would be to make changes to the JDK itself, i.e., contribute to OpenJDK.
Since there is no need to use --initialize-at-build-time=, removing that from the native-image command line is the recommended solution for now.
