This patch implements that check. src/java.base/share/classes/jdk/internal/foreign/abi/AbstractLinker.java line 114: > 112: private void checkLayouts(FunctionDescriptor descriptor) { > 113: descriptor.returnLayout().ifPresent(this::checkLayoutsRecursive); > 114: > descriptor.argumentLayouts().forEach(this::checkLayoutsRecursive); Storing `this::checkLayoutsRecursive` in a local variable allows the `Consumer` to be reused for the return and argument layouts, thus only one lambda class and instance needs to be allocated instead of two. Suggestion: final Consumer<MemoryLayout> checker = this::checkLayoutsRecursive; descriptor.returnLayout().ifPresent(checker); descriptor.argumentLayouts().forEach(checker); ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/13161#discussion_r1147232059
