> Hi.
> We found that the following test case fails with a StackOverFlowError exception:
> {code:java}
> test() {       
>    SetUniqueList l = new SetUniqueList(new LinkedList<Object>()) ;       
>    l.add((Object) l) ;   
> }{code}
> The add() execution traps into an infinite recursion which crashes the program.
> From the stack trace, we found that the infinite recursion occurs
> at AbstractList.hashCode() since it invokes hashCode() of each of its elements.
