Description

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.
