> 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.
