> Error deserializing empty array (which represents null)

>
> Serializing null arrays results in an empty byte[]. The deserialization logic
> in PArrayDataType#createPhoenixArray has a check to return null if the
> provided byte[] is empty, however it checks the length of the byte[] rather
> than the provided length parameter. Note that the provided byte[] is
> typically the whole underlying row; it has to be interpreted only from offset
> to length.
> Therefor, the check has to be replaced with a check on length rather than on
> bytes.length.
