>             Project: WildFly
>          Issue Type: Bug
>    Affects Versions: 8.1.0.Final, 8.2.0.Final
>            Reporter: Jeroen Wielandt
>            Assignee: Eduardo Martins

> The clone function uses sublist  to set the new list of interceptors. 
> public InterceptorContext clone() {
>      ....
>         clone.setInterceptors(interceptors.subList(next, interceptors.size()));
>         return clone;
>     }
> This will keep a reference to the original list around. So the original list will never be released. Chaining clone multiple times will eventually cause an out of memory because each sublist grows slightly.
