-------------------------------------

Yes it is true, It would leak next nodes if the next nodes not yet accessed for restoring, Thanks Johnu.

> Here is the implementation of the destroy function in LinkedList node
>   @Override
>   public void destroy() throws RetrieveDurableEntityError {
>     m_holder.destroy();
>     if (null != m_item) {
>       m_item.destroy();
>       m_item = null;
>     }
>     if (null != m_next) {
>       m_next.destroy();
>       m_next = null;
>     }
>   }
> Next is destroyed only when m_next is not null. m_next can also be null if next item is not loaded into memory from PMem. It is required to first restore the item using getNext and then call destroy.
