Retrieving results from ARRAY and ROW

Hi all!

(Using pg-8.4 with postgresql-8.4-701.jdbc4.jar)
I have the following (simplified for example) schema:

CREATE TABLE person(id INTEGER, name VARCHAR);
INSERT INTO person(id, name)
VALUES (1,'James'),(2, 'Jack');
CREATE TABLE person_dep(person_id INTEGER, dep VARCHAR);
INSERT INTO person_dep(person_id, dep)
VALUES (1,'Dep1'),(1,'Dep2');

SELECT p.id, p.name
, ARRAY(SELECT ROW(dep.person_id, dep.dep)
FROM person_dep dep
WHERE dep.person_id = p.id) AS my_array
FROM person p
WHERE p.id IN (1,2);

id | name | my_array
----+-------+-------------------------
1 | James | {"(1,Dep1)","(1,Dep2)"}
2 | Jack | {}
(2 rows)

The problem is that I'm not able to retrieve the results from "my_array" using rs.getArray("my_array").getArray(), which results in:
org.postgresql.util.PSQLException: Method org.postgresql.jdbc4.Jdbc4Array.getArrayImpl(long,int,Map) is not yet implemented.

Does someone know any better way to write this query which makes it work with JDBC? I know I can write 2 sub-selects instead of one and have each column return and array of integer[] and varchar[], but I'm trying to avoid having more than *one* sub-select.

My actual query involves a "WITH RECURSIVE" sub-select which retrieves <id,name> pairs for the parent of each node to form a path up to the top-most parent, which makes several sub-selects involving CTE unattractive.
