Compile error: Variable length argument + Method reference

Eclipse IDE for Enterprise Java and Web Developers
Version: 2021-09 4.21.0

Passing a method reference to a method with variable length arguments in a function interface will cause a compilation error.
This happens regardless of the Java version of the project.
This problem does not occur in Eclipse 2021-06 4.20.



public static void main(String[] args) {
	String s1 = hoge1(String::new);
	String s2 = hoge2(String::new);	// Error. See the attached file.
}
static <T> T hoge1(Supplier<T> sup) {
	return null;
}
static <T> T hoge2(Supplier<T>... sup) {
	return null;
}
