This static definition in some of the examples:

private static MemoryAddress allocatePointer(MemoryAddress value, NativeScope scope) {
+         var addr = scope.allocate(C_POINTER);
+         var handle = C_POINTER.varHandle(long.class);
+         handle.set(addr, value.toRawLongValue());
+         return addr;
+     }

seems unnecessary, since it can just be replaced by two lines:

var addr = scope.allocate(C_POINTER);
MemoryAccess.setAddress(addr, 0, value);
