TIL that order of iteration is different in ArrayDequeu vs Stack: Stack.push() adds to the "end of stack" (it just calls Vector.add()), while ArrayDeque.push adds "first element" Luckily for us there was only one place which depend on this. It's small method `javax.swing.text.html.HTMLDocument.HTMLReader#getPathTo`. I've changed method to use ArrayList instead. ------------- PR: https://git.openjdk.java.net/jdk/pull/5294
