Please investigate code:

while (currentNode.getNextSibling() == null && currentNode.getParent() != parent) {
                    currentNode = currentNode.getParent();
                }
                currentNode = currentNode.getNextSibling();

It might a reason why parent node is not required, as we exist "while " by null sibling, that is reasonable
