> Selecting more than two individual array elements in a query results in an
> ArrayIndexOutOfBoundsException thrown from ScanRegionObserver.
> An example of a query that will trigger this situation is as follows:
> {code}select arr[1], arr[2], arr[3] from table_with_array{code}
> The cause appears to be the replaceArrayIndexElement method in
> ScanRegionObserver. It removes a Cell for each array reference in the query,
> with the intention of replacing them with a reduced Cell that only contains
> the requested values of the array. The current impl attempts to remove the
> same KeyValue multiple times, and in the end attempts to remove more
> KeyValues than there are in the original list.
