Ensure JEP 454 (Foreign Function and Memory API) works correctly with Mandrel for JDK 22 (24.0)
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);

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.
