I think the fix is in the wrong place. We should fix the underlying vector.
I was able to fix the problem with a small change to
BaseRepeatedValueVector.BaseRepeatedMutator:
```java
@Override
public void startNewValue(int index) {
while (offsets.getValueCapacity() <= index) {
offsets.reAlloc();
}
offsets.getMutator().setSafe(index+1,
offsets.getAccessor().get(index));
setValueCount(index+1);
}
```
We shouldn't need to make any change in the writer.
