Return the value converted to a byte
or the specified alternate value if the original value is null. Note,
this method still throws {@link IllegalArgumentException} if the value
is not null and could not be converted.

@param	value
The value to be converted
@param	nullValue
The value to be returned if {@link value} is null. Note, this
value will not be returned if the conversion fails otherwise.
@throws	IllegalArgumentException
If the value cannot be converted
