I have a sample function, whit takes an array argument

CREATE OR REPLACE FUNCTION arraySum(
multiplier bigint,
valuelist bigint[],
OUT result int
) AS
$$
BEGIN
result = 0;
FOR idx IN array_lower(valuelist, 1)..array_upper(valuelist, 1) LOOP
result = result + multiplier * valuelist[idx];
END LOOP;
RETURN;
END;
$$ LANGUAGE plpgsql SECURITY DEFINER;

When I call this function directly via JDBC or using proxool I get a
result, when doing it via c3p0 or dbcp I get an exception -

Long[] array = { 1L, 2L };
PreparedStatement ps = conn.prepareStatement(
"SELECT * FROM arraySum(?, ?)");
ps.setLong(1, 3L);
ps.setArray(2, conn.createArrayOf("bigint", array));
ps.execute();
