Specificaition of method VaList::skip is rather short
> Skips a number of elements with the given memory layouts, and advances this variable argument list's position.
It's not perfectly clear what would for example produce the following code
try (var session = MemorySession.openConfined()) {
VaList vaList = VaList.make(builder -> builder.addVarg(ValueLayout.JAVA_INT, 77)
.addVarg(ValueLayout.JAVA_LONG, -78),
session);
vaList.skip(ValueLayout.JAVA_DOUBLE, ValueLayout.JAVA_BOOLEAN);
System.out.println(vaList.nextVarg(ValueLayout.JAVA_INT));
}
On MacOS x86 the result is
-78
In the OpenJDK implementation behaves correctly, the spec of ::skip would benefit from more detailed explaination or some references or hints.

JDK-8290186 Specification of method j.l.foreign.VaList::skip deserves clarification
