Description

With JDK 22, JEP 454 went out of preview. For GraalVM this currently means needing to ship svm-foreign.jar in the correct location of the distro. Specifically, next to svm.jar in $MANDREL_HOME/lib/svm/builder. Then, native-image builds pick up the jar and add it to the module path when the generator runs.

However, after fixing that, not everything seems to be fully working (might be my test case, but still).

How To Reproduce

$ 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);
			// 5. Copy the strings from on-heap to off-heap
			for (int i = 0; i < javaStrings.length; i++) {
				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);
		}
	}

Recommendations:
 HEAP: Set max heap for improved and more predictable memory usage.

Configuration:

Mandrel 24.0 with JDK 22+33.

Expected behavior

Reproducer works the same as when run with java:

$ java --enable-native-access=ALL-UNNAMED FFM
Test passed! List sorted: [car, cat, dog, mouse]

Additional context

Where svm-foreign.jar is located changed from 23.1 (JDK 21) to 24.0 (JDK 22). It used to live in an svm-preview folder. There also seems to be a difference on how --enable-native-access works (one cannot silence the warning with the switch in native-image).

GraalVM for JDK 22 community (self-built) seems to have a similar issue.

Going by the discussion in oracle#8012, specifically this:

Foreign Function and Memory API support (OpenJKD Project Panama): Since support in native image
is still under development, it needs to be enabled explicitly at image build time (and then some things
will work, and some things will not work).
https://github.com/oracle/graal/pull/7980

It might not be 100% ready yet for JDK 22.

There also seems to be a difference on how --enable-native-access works (one cannot silence the warning with the switch in native-image).

-J--enable-native-access=ALL-UNNAMED needs to be passed to native-image at build time to achieve this silencing.

I've tested this with the GraalVM for JDK 22 Community release here (GA released yesterday):
https://github.com/graalvm/graalvm-ce-builds/releases/tag/jdk-22.0.0

Seems to have the same issue:
