Same comment as with pop, would using Deque instead of Stack make sense?
> same linkedlist code different behavior between groovy and java

> Key: GROOVY-6396
> URL: https://issues.apache.org/jira/browse/GROOVY-6396
> Project: Groovy
> Issue Type: Bug
> Components: jdk conflict
> Reporter: boshi
> Labels: breaking
>
> I am using `linkedlist` as a stack in groovy
> as doc says, `pop()` take elm from the first
> Stack Method Equivalent Deque Method
> push(e) addFirst(e)
> pop() removeFirst()
> so a `linkedlist` [1,2,3] should pop() 1 2 3
> and it does in Java, but does NOT in groovy. WHY?
> test below
> {code:title=A.java}
> import java.util.*;
>
> public class A{
>
>
> public static void main(String[] args){
>
> String[] x = "1/2/3/".split("/");
> LinkedList <String> stack = new LinkedList<String>(Arrays.asList(x));
> System.out.println(stack.pop());
> }
> }
> {code}
> compile and run
> {noformat}
> $ javac A.java
