> Out of order writes using setSafe

>
> Key: ARROW-8909
> URL: https://issues.apache.org/jira/browse/ARROW-8909
> Project: Apache Arrow
>  Issue Type: Bug
>  Components: Java
>Reporter: Saurabh

> I noticed that calling setSafe on a VarCharVector with indices not in 
> increasing order causes the lastIndex to be set to the index in the last call 
> to setSafe.
> Is this a documented and expected behavior ?
> Sample code:
> {code:java}
> import java.util.Collections;
> import lombok.extern.slf4j.Slf4j;
> import org.apache.arrow.memory.RootAllocator;
> import org.apache.arrow.vector.VarCharVector;

> import org.apache.arrow.vector.types.pojo.Field;
> import org.apache.arrow.vector.types.pojo.Schema;
> import org.apache.arrow.vector.util.Text;
> @Slf4j
> public class ATest {
>   public static void main() {
> Schema schema = new 
> Schema(Collections.singletonList(Field.nullable("Data", new 
> ArrowType.Utf8(;
> try (VectorSchemaRoot vroot = VectorSchemaRoot.create(schema, new 
> RootAllocator())) {
>   VarCharVector vec = (VarCharVector) vroot.getVector("Data");
>   for (int i = 0; i < 10; i++) {
> vec.setSafe(i, new Text(Integer.toString(i) + "_mtest"));
>   }
>   // vec.setSafe(0, new Text(Integer.toString(0) + "_new"));
>   vec.setSafe(7, new Text(Integer.toString(7) + "_new"));
>   vroot.setRowCount(10);
>   log.info(vroot.contentToTSVString());
> }
>   }
> }
> {code}
>  
> If I don't set the 0 or 7 after the loop, I get all the 0_mtest, 1_mtest, 
> ..., 9_mtest entries.
> If I set index 0 after the loop, I only see 0_new entry; other entries are ""
> If I set index 7 after the loop, I see 0_mtest, ..., 5_mtest, 7_new; other 
> entries are ""
