   - ToArrayCallWithZeroLengthArrayArgument
   The performance of the empty array version is the same, and sometimes even better, compared
   to the pre-sized version. Also, passing a pre-sized array is dangerous for a concurrent or
   synchronized collection as a data race is possible between the <code>size</code> and <code>toArray</code>
   calls. This may result in extra <code>null</code>s at the end of the array if the collection was concurrently
   shrunk during the operation.</p>
