Problem on htmldb 1.6.1.00.03 - not present in 1.6.0.0.87

Question

I really need help.
I have an application running for a year in which many reports and SVG graphs are based on queries in the form as you can see below.
On my linux oracle 10.1.0.3 and htmldb1.6.0.0.87 all is ok and month show ordered correctly Jan, Feb, Mar, etc
When I installed a windows machine on Oracle10g 10.2.0.1.0 and HTMLDB 1.6.1.00.03
All reports and graphs give me Jan, Apr, Jul, Feb, ...
Running the query in SQLWORKSHOP shows correct data with month ordered, in run-time it does not.
I can solve the problem in a report by forcing a "order by b.month" but in clustered and line charts done in SVG if i add an order by clause to all series at run-time I get an error "sql statement not terminated ..." the view source shows a union of all my series with order by which doesnt even run in sqlworkshop.
The question is what has changed in this version of htmldb to cause this ordering problem.
QUERY EXAMPLE:
SELECT
TO_CHAR(TO_DATE(b.month,'MM'),'Mon') YMonth,
0 -- replaced o for real query for you to test
) pipeline_value
FROM (SELECT month
FROM
(select level month
from dual
connect by level <= 12)
) b
group by b.month

Hi Scott,
I tried to reproduce problem on htmldb.oracle.com and it worked fine I could not reproduce problem. I then did some further testing and discovered the following:
My problem is shown not dependant of HTMLDB versions but Oracle versions:
My new machine I installed Oracle 10GR2 10.2.0.1.0 in SQLPLUS I see the problem so it has nothing to do with HTMLDB. In htmldb.oracle.com a did a select * from v$version and the version is 10.1.0.4.0.
My conclusion is the following query has diferent behaviour in oracle db 10.2.0.1.0 compared to all earlier versions. Earlier versions show months ordered in new version months are not shown in order.
SELECT TO_CHAR(TO_DATE(b.month,'MM'),'Mon') YMonth
FROM
(SELECT month FROM (select level month from dual connect by level <=12)) b
group by b.month
This causes lots of errors in SVG graphs. If I remove the group by in this select the problem does not show but in the final solution I cannot remove it(this is just a simplification to show the error)
If you have access to a DB 10.2.0.1.0 try this is sqlplus and compare it with a run in SQLWORKSHOP of the htmldb.oracle.com.
Thanks
