Others are more expert than I but I believe the difference is that f1/f2
invokes are using hard Java Objects and f3/f4 invokes are using MethodHandles
with generic arguments.

thx, Jim, I hava tried your solution and it works. but it needs to invoke
java method so it's more complex. After all, what's the different between
f1, f2 and f4.

It could have inferred that you meant to pass in a single element object array.

Nashorn needs a bit more to determine that you wanted to convert to an java
object array.
System.out.println(nashorn.eval("var ObjectArray =
Java.type('java.lang.Object[]'); f4(Java.to([1,2], ObjectArray))")
Hi, all, I'am trying to add a function to nashorn engine's bindings, and
these methods I have tried:
public class MyFunction implements Function {
@Override
public Object apply(Object[] objects) {
return Arrays.toString(objects);
}
public Object f2(Object[] objects) {
