> Hi all,
> In one of my projects I wanted to use copy on write list. I slightly improved this implementation and thought it would be nice to add it to commons collections, as I couldn't find something like this.
> Implementation details:
> - the original list is wrapped with CopyOnWriteList,
> - on modifications the original list is copied and copy is used instead,
> - for iterators before modification, the cursor index is used and then new iterator is set on on required position (this can't be done for abstract collections)
> I hope there is no flaw in my designs,
> Best regards, 
> Radek Smogura
