Jpub generated collections and SLOW RETRIEVAL

Question

Oracle 8.1.6 EE
SQLJ/JDBC 8.1.7
I use jpub to generate oracle specific usertypes (i.e) -usertypes=oracle. All the classes generate fine and I can use them in my code. The problem is that when I try to use the getArray() or getElement() methods from the generated collection class, it is REALLY SLOW. On the order of two minutes to retrieve 30 records. Using a test harness in SQLPLUS the retrieval is fast. On the order of milliseconds.
I call a stored procedure that returns the array of objects.
The object looks like this ...
CREATE OR REPLACE TYPE account_item AS OBJECT
id number,
name varchar2(200),
tag_id varchar2(50),
state varchar2(20),
zip varchar2(20),
primary_contact varchar2(200),
phone varchar2(20),
status varchar2(50),
broker varchar(200)
The collection type looks like ...
CREATE OR REPLACE TYPE account_item_list AS TABLE OF account_item
Does anyone from the jdbc/sql group have any idea why this would be happening ??
Thanks.

Ad (1): No idea. Retrieving 9 records each with a nested table of 30 items is practically instantaneous. (Using 9.0.1 client and server and OCI.) Are you using thin or OCI JDBC? Maybe there is an issue connecting between an 8.1.7 client and a 8.1.6 server? (The 8.1.6 JPub runtime had bad performance. 8.1.7 is much improved and should be about equal with 9.0.1.)
Ad (2): With the SQL definitions of account_item and account_item_list and the following table in the scott/tiger schema:
create table accounts (id number, account account_item_list)
nested table account store as accounts_nested_table;
you can run JPublisher as follows:
jpub -user=scott/tiger -sql=account_item:AccountItem,account_item_list:AccountItemList
Then use the following program TestAccount.sqlj (can't resist SQLJ here):
import java.sql.SQLException;
import oracle.sqlj.runtime.Oracle;
import sqlj.runtime.ResultSetIterator;
public class TestAccount
{ #sql public static iterator Iter (int id, AccountItemList account);
public static void main(String[] args) throws SQLException
{ Oracle.connect("jdbc:oracle:oci:@","scott","tiger");
Iter it;
#sql it = { select id, account from accounts };
while (it.next())
printList(it.id(), it.account().getArray());
it.close(); Oracle.close();
private static void printList(int id, AccountItem[] items) throws SQLException
{ System.out.print("List "+id+" [");
for (int i=0; i<items.length; i++)
{ System.out.print(items[i].getId());
if (i < items.length-1 ) System.out.print(",");
System.out.println("]");
Compile everything with:
sqlj *.java *.sqlj
And then run:
java TestAccount
