> An ArrayIndexOutofBoundsException is thrown when the toArray(T[]) method is invoked,
under load test with multiple threads. Concurrent updates to the collection results in changing
Iterator sizes. As per the Javadocs, the result of the toArray(T[]) should return as much
elements possible from the Collection. 
> A toArray(T[]) method override has been implemented in ConcurrentSkipListSet and the
bounds check has been included in the base class AbstractCollection to prevent this exception.
