Problem with JDBC version 8.0/1 vs. 7.4

Hello,

I'm trying to run the SQL statement found below.  Meaning, if I have a
String sql set to the big hunk of text below the '----', I then call
    ResultSet rs = statement.executeQuery(sql);

When I use the JDBC Driver v7.4, everything works just fine (and it
returns some rows).  But when I use JDBC Driver v8.0 or v8.1, I get the
following Exception:

org.postgresql.util.PSQLException: No results were returned by the
query.
    at
org.postgresql.jdbc2.AbstractJdbc2Statement.executeQuery(AbstractJdbc2Statement.java:240)


Does anyone know what is causing this problem or how to fix it?  For now
I'm sticking with the 7.4 driver.

Thanks,
-- Bob
