NullPointerException is thrown when index intersection is chosen by the 
IntroduceSelectAccessMethodRule and there's a between operator.

DDL: 

create index idx_custkey on Orders (o_custkey) type btree;
create index idx_orderpriority on Orders (o_orderpriority) type btree;

Query:

select o_custkey, o_orderkey, o_orderstatus from Orders
where
 o_orderpriority = '1-URGENT' and
 o_custkey between 40 and 43
order by o_custkey, o_orderkey

Exception:

java.lang.NullPointerException: null

org.apache.asterix.optimizer.rules.am.IntroduceSelectAccessMethodRule.connectAll2ndarySearchPlanWithIntersect(IntroduceSelectAccessMethodRule.java:264)
 ~[classes/:?]
 at 
org.apache.asterix.optimizer.rules.am.IntroduceSelectAccessMethodRule.intersectAllSecondaryIndexes(IntroduceSelectAccessMethodRule.java:232)
 ~[classes/:?]

Workaround:

Use "<=" and ">=" instead of "between"
