> In case the start of the slice is zero, a new offset buffer is unnecessarily
> allocated:
> https://github.com/apache/arrow/blob/master/java/vector/src/main/java/org/apache/arrow/vector/BaseVariableWidthVector.java#L743
> Since the starting offset is zero, the offset pointers don't have to be
> updated.
