Jochen Kemnade commented on GROOVY-6396:
----------------------------------------
That depends on whether I'm currently thinking in Stack or in List semantics.
And I think there are more questions that we need to ask ourselves:
Which output do we expect from the code snipped I posted above?
I'm not even sure about that one. Depends on whether you come from Stack or
JavaScript (where Array.push pushes to the end).
What is the use case for the default method?
This will only be used for a List instance that does not implement push itself,
like {{[]}} in a Groovy script. How should that behave?
Do we want a change in behavior from Groovy 2.4 to Groovy 2.5, which is a minor
level release after all?

> Key: GROOVY-6396
> URL: https://issues.apache.org/jira/browse/GROOVY-6396
> Project: Groovy
> Issue Type: Bug
> Components: jdk conflict
> Reporter: boshi
> Assignee: Paul King
> Labels: breaking
> Fix For: 2.5.0-alpha-1
>
>
> 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
> $ java A
> 1
> {noformat}
> runing in groovy
> {noformat}
> $ ln -s A.java A.groovy
> $ groovy A.groovy
> 3
> {noformat}
> here is my java and groovy version
> {noformat}
> $ java -version
> java version "1.6.0_51"
> Java(TM) SE Runtime Environment (build 1.6.0_51-b11-457-11M4509)
> Java HotSpot(TM) 64-Bit Server VM (build 20.51-b01-457, mixed mode)
