Description

A NullPointerException was reported by Harm-Jan Zwinderman on derby-user:
http://mail-archives.apache.org/mod_mbox/db-derby-user/201211.mbox/%3C50B66527.5040906%40gmail.com%3E

I've managed to reproduce it on 10.9.1.0 like this:

ij version 10.9
ij> connect 'jdbc:derby:memory:db;create=true';
ij> create table t(x double);
0 rows inserted/updated/deleted
ij> insert into t values (0);
1 row inserted/updated/deleted
ij> prepare ps as 'insert into t select 1 from t order by x';
ij> execute ps;
1 row inserted/updated/deleted
ij> execute ps;
2 rows inserted/updated/deleted
ij> execute ps;
4 rows inserted/updated/deleted
ij> execute ps;
ERROR XJ001: Java exception: ': java.lang.NullPointerException'.
