…rupts struct and array data `OffHeapColumnVector.reserveInternal()` will only copy already inserted values during reallocation if `data != null`. In vectors containing arrays or structs this is incorrect, since there field `data` is not used at all. We need to check `nulls` instead. Adds new tests to `ColumnVectorSuite` that reproduce the errors. Author: Ala Luszczak <[email protected]> Closes apache#19308 from ala/vector-realloc. (cherry picked from commit d2b2932) Signed-off-by: Ala Luszczak <[email protected]>

@ala can you close this one? The merge script does not do that for backports. |

@hvanhovell Sure. Thanks! |
