> There are several methods that modify the BaseDataValueVector#data field. 
> Some of them, such as BaseDataValueVector#exchange, do not change allocationSizeInBytes. 
> Therefore, if BaseDataValueVector#exchange was executed for vectors with different size, *ValueVector#reAlloc may create a buffer of insufficient size.
