使用GraalVM将Quarkus应用生成DLL供C#调用时创建Isolate报错的问题求助

我现在需要把Quarkus应用打包成DLL文件，试过IKVM、IKVM.net、JNI这些方法都没成功，目前打算用GraalVM来实现。

我已经能成功编译Java类，用的命令是：

javac *.java

也能生成DLL，命令是：

native-image --shared -H:Name=dbexample -H:-CheckToolchain --enable-native-access=ALL-UNNAMED --no-fallback

用dumpbin /EXPORTS dbexample.dll查看生成的DLL，能看到Java里的方法确实被导出了，但调用的时候却报错，看起来是内存访问相关的通用错误，比如提示“Exited Thread 44280”。

我的Java代码 #

import org.graalvm.nativeimage.IsolateThread;
import org.graalvm.nativeimage.c.function.CEntryPoint;

import org.graalvm.nativeimage.Isolates;
import org.graalvm.nativeimage.Isolates.CreateIsolateParameters;

public final class LogicConnectionImpl implements LogicConnection {

    @CEntryPoint(name = "IsolateCreate")
    public static IsolateThread createIsolate(@SuppressWarnings("unused") IsolateThread thread) {
        var context = Isolates.createIsolate(CreateIsolateParameters.getDefault());
        return context;
    }

    @CEntryPoint(name = "doSomething")
    public static void doSomething(@SuppressWarnings("unused") IsolateThread thread) {
        System.out.println("Hello, World from inside JAVA!");
    }

    @CEntryPoint(name = "test")
    public static int test(@SuppressWarnings("unused") IsolateThread thread) {
        return 23;
    }

    @CEntryPoint(name = "test2")
    public static void test2(@SuppressWarnings("unused") IsolateThread thread, int value) {
        int value2 = value + 1;
        System.out.println("Hello, World from inside JAVA!");
    }

    public void test3(String thisTest) {
        System.out.println("Hello, World from inside JAVA! " + thisTest);
    }
}

我的C#代码 #

using System;
using System.Runtime.InteropServices;

class Program
{
    // Define the P/Invoke signatures
    [DllImport("dbexample.dll", EntryPoint = "doSomething")]
    public static extern void DoSomething(IntPtr thread);

    [DllImport("dbexample.dll", EntryPoint = "test")]
    public static extern int Test(IntPtr thread);

    [DllImport("dbexample.dll", EntryPoint = "test2")]
    public static extern void Test2(IntPtr thread, int value);

    [DllImport("dbexample.dll", EntryPoint = "IsolateCreate")]
    public static extern IntPtr IsolateCreate(IntPtr thread);


    static void Main(string[] args)
    {
        try
        {
            IntPtr isolateThread = IsolateCreate(IntPtr.Zero);

            if (isolateThread == IntPtr.Zero)
            {
                Console.WriteLine("Failed to create IsolateThread.");
                return;
            }
        
            // Call the methods from the DLL
            DoSomething(isolateThread);
            int result = Test(isolateThread);
            Console.WriteLine("Result from test: " + result);
            Test2(isolateThread, 42);
        }
        catch (Exception ex)
        {
            Console.WriteLine("An error occurred: " + ex.Message);
        }
    }
}

报错发生在这一行：

IntPtr isolateThread = IsolateCreate(IntPtr.Zero);

我觉得问题出在方法参数（IntPtr.Zero）上。根据我了解到的信息，调用doSomething这类方法不能直接传IntPtr.Zero，必须用Java应用里createIsolate方法返回的IsolateThread。但问题是，被导出到DLL的createIsolate方法本身也需要一个IsolateThread类型的参数，而在C#里我只能传IntPtr.Zero进去，这就陷入了死循环。

感觉我离成功只差一步，但就是找不到这个关键的调整点，有没有大佬能帮我看看？
