Review comment:
1. To reduce code duplication
2. To avoid warnings all over the place. Idea thinks that
`oldInnerNodesStack.peek()` may return `null`, so the class looks like a
Christmas tree, which may mask real problems highlighted as warnings. With this
method, we let Idea know that it cannot return `null`.
