Release Note: Base64.Encoder and Base64.Decoder Methods Can Throw OutOfMemoryError

The behavior of `Base64.Encoder.encode` and `Base64.Decoder.decode` methods have been changed for large arrays. The methods previously threw an unspecified exception, such as, `NegativeArraySizeException`. The new behavior throws an `OutOfMemoryError` exception if the `encode` and `decode` methods fail to allocate the output array/buffer or memory.
