    Description

      New JDK 21 method in java.util.List addLast has a void return type. This clashes with the existing boolean return from the same method in AbstractLinkedList:

      java.util.List {
    default void addLast(E e);
}

org.apache.commons.collections4.list.AbstractLinkedList {
    public boolean addLast(final E o);
}
