graal_tear_down_isolate stuck when Java2D Disposer is running

[k-x7]

Describe the issue
I have created a small shared lib using native image, which call ImageIO.read(...).
when I call graal_tear_down_isolate from the C code the program will not return anything after printing an error :

Exception while removing reference.

My assumption is Disposer when the thread interrupted it will just print the error and call wait() somewhere else, which will stuck in waiting state or the infinite while loop.

I tried to get Java2D Disposer thread and call interrupt() many times without success.

Steps to reproduce the issue

1. create a new java class GetImageInfo.java:

import org.graalvm.nativeimage.IsolateThread;
import org.graalvm.nativeimage.c.function.CEntryPoint;
import org.graalvm.nativeimage.c.type.CCharPointer;
import org.graalvm.nativeimage.c.type.CTypeConversion;

import javax.imageio.ImageIO;

import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;

public class GetImageInfo {

    // For Testing
    public static void main(String[] args) {
        printImageInfo(args[0]);
    }

    @CEntryPoint(name = "get_image_info")
    private static void GetImageInfo(IsolateThread thread, CCharPointer path) {
        String Path = CTypeConversion.toJavaString(path);
        printImageInfo(Path);
    }

    private static void printImageInfo(String path) {
        System.out.println("loading img in path: " + path);
        try {
            BufferedImage input = ImageIO.read(new File(path));
            System.out.println("Height: " + input.getHeight() + ", Width: " + input.getWidth());
        } catch (IOException e) {
            System.err.println(e);
        }
    }

}

2. run javac:

javac GetImageInfo.java

3. create config file for JNI and reflection:

java -agentlib:native-image-agent=config-output-dir=META-INF/native-image GetImageInfo PATH_TO_ANY_IMAGE.jpg

output:

loading img in path: sample.jpg
Height: 720, Width: 1200

4. create a shared lib:

native-image -H:Name=libgetimageinfo GetImageInfo --shared

5. create a c file main.c:

#include <stdio.h>
#include <stdlib.h>

#include "libgetimageinfo.h"

int main(int argc, char **argv) {
    // printf("[*] using libgetimageinfo main:\n");
    // run_main(argc, argv);

    printf("[*] using libgetimageinfo centrypoint:\n");
    graal_isolate_t *isolate = NULL;
    graal_isolatethread_t *thread = NULL;

    if (graal_create_isolate(NULL, &isolate, &thread) != 0) {
        fprintf(stderr, "initialization error\n");
        return 1;
    }

    get_image_info(thread, argv[1]);

    if (graal_tear_down_isolate(thread) != 0) {
        fprintf(stderr, "shutdown error\n");
        return 1;
    }

    // if (graal_detach_all_threads_and_tear_down_isolate(thread) != 0) {
    //     fprintf(stderr, "shutdown error\n");
    //     return 1;
    // }
}

6. compile main.c:

gcc -L$(pwd) -I$(pwd) -Wall -o main main.c -lgetimageinfo

7. run main:

env LD_LIBRARY_PATH=$(pwd) ./main PATH_TO_ANY_IMAGE.jpg

[*] using libgetimageinfo centrypoint:
loading img in path: qrcode.jpg
Height: 720, Width: 1200
Exception while removing reference.

now the program stuck forever.

8. calling ps in the running program will show the following:

ps -T -p $(pidof main)

    PID    SPID TTY          TIME CMD
1091924 1091924 pts/12   00:02:43 main
1091924 1091931 pts/12   00:00:00 Java2D Disposer

Hi @k-x7

we are currently working on #4921 to quite generally improve support for AWT and related technologies. Once that is merged (work is in progress already, so expect that to be merged in the next months, but no definite ETA), we will have a look at this. Could easily be affected by the current changes so we will have a look once the major changes are in.

any updates on this?? Facing similar issue while using a dependency that relies on awt. Even tried it with the latest graalvm dev builds, doesn't work. The issue described by @k-x7 is still reproducible with:

GraalVM Runtime Environment GraalVM CE 23-dev+24.1 (build 23+24-jvmci-b01)
