GraalVM for JDK 22 Community: ForeignFunctionsRuntime$UnregisteredForeignStubException: [FFM] Cannot perform downcall with leaf type (long,long,long,long,long)void as it was not registered at compilation time.

[jerboaa]

Describe the issue
JDK 22 made "Foreign Function & Memory API" final. See JEP 454. I've tested this with the latest GraalVM for JDK 22 Community release and it doesn't seem to be fully functional. Is this known?

Steps to reproduce the issue

$ cat FFM.java
import static java.lang.foreign.ValueLayout.ADDRESS;
import static java.lang.foreign.ValueLayout.JAVA_INT;
import static java.lang.foreign.ValueLayout.JAVA_LONG;

import java.lang.foreign.Arena;
import java.lang.foreign.FunctionDescriptor;
import java.lang.foreign.Linker;
import java.lang.foreign.MemorySegment;
import java.lang.foreign.SymbolLookup;
import java.lang.foreign.ValueLayout;
import java.lang.invoke.MethodHandle;
import java.lang.invoke.MethodHandles;
import java.lang.invoke.MethodType;
import java.util.Arrays;
import java.util.List;

public class FFM {
	static int compare(MemorySegment elem1, MemorySegment elem2) {
		MemorySegment s1 = elem1.get(ADDRESS.withTargetLayout(ADDRESS), 0);
		String one = s1.getString(0);
		MemorySegment s2 = elem2.get(ADDRESS.withTargetLayout(ADDRESS), 0);
		String two = s2.getString(0);
		assert one != null;
		assert two != null;
		int value = one.compareTo(two);
		if (value == 0) {
			return 0;
		} else {
			return value < 0 ? -1 : 1;
		}
	}

	public static void main(String[] args) throws Throwable {
		// 1. Find foreign function on the C library path
		Linker linker = Linker.nativeLinker();
		SymbolLookup stdlib = linker.defaultLookup();
		MethodHandle qsort = linker.downcallHandle(stdlib.find("qsort").orElseThrow(),
				FunctionDescriptor.ofVoid(ADDRESS, JAVA_LONG, JAVA_LONG, ADDRESS));
		MethodHandle comparHandle = MethodHandles.lookup().findStatic(FFM.class, "compare",
				MethodType.methodType(int.class, MemorySegment.class, MemorySegment.class));
		// 2. Allocate on-heap memory to store four strings
		String[] javaStrings = { "mouse", "cat", "dog", "car" };
		// 3. Use try-with-resources to manage the lifetime of off-heap memory
		try (Arena offHeap = Arena.ofConfined()) {
			MemorySegment comparFunc = linker.upcallStub(comparHandle,
					/*
					 * A Java description of a C function implemented by a Java method!
					 */
					FunctionDescriptor.of(JAVA_INT,
							ValueLayout.ADDRESS.withTargetLayout(ADDRESS),
							ValueLayout.ADDRESS.withTargetLayout(ADDRESS)),
					offHeap);
			// 4. Allocate a region of off-heap memory to store four pointers
			MemorySegment pointers = offHeap.allocate(ValueLayout.ADDRESS, javaStrings.length);

				MemorySegment cString = offHeap.allocateFrom(javaStrings[i]);
				pointers.setAtIndex(ValueLayout.ADDRESS, i, cString);
			}
			// 6. Sort the off-heap data by calling the foreign function
			qsort.invoke(pointers, (long) javaStrings.length, ADDRESS.byteSize(), comparFunc);

			// 7. Copy the (reordered) strings from off-heap to on-heap
			for (int i = 0; i < javaStrings.length; i++) {
				MemorySegment cString = pointers.getAtIndex(ValueLayout.ADDRESS, i);
				javaStrings[i] = cString.reinterpret(ADDRESS.byteSize()).getString(0);
			}
		} // 8. All off-heap memory is deallocated here
		List<String> list = Arrays.asList(javaStrings);
		if (!Arrays.equals(javaStrings, new String[] { "car", "cat", "dog", "mouse" })) {
			throw new AssertionError("Lists not sorted! Got:" + list);
		} else {
			System.out.println("Test passed! List sorted: " + list);

More details
Perhaps I'm missing some setup work and it then works, but for now it fails at runtime for me:

This issue is related to #8113

[fniephaus]

FFM API is only partially working in Native Image. The release notes mention that, so things are expected not to work. Could we please close this ticket and instead use #8113 to track this in one place for all users?

[jerboaa]

Closing in favour of #8113.
