Repairing Code Style Issues

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 size and toArray
calls. This may result in extra nulls at the end of the array if the collection was concurrently
shrunk during the operation.
