Still not sure whose fault is it, either javac creates invalid bootstrap methods or this is runtime problem. Feel free to forward it to appropriate area.

Minimized testcase:

interface SAM<T> {
    T get();
}

public class Test {
    public static void main(String[] args) {
        SAM<SAM> sam = () -> Object::new;
        SAM temp = sam.get()::get;
    }
}
