JDBC rewriting a bad query?

I have an issue that I am trying to understand. We had an issue where we
had a query with a syntax error, but we would not get any errors in the log
files. It turns out that the query was being shortened by the time it got
to the server and not causing an error. The version of jdbc driver we are
running is 8.2-507

QUERY FROM WEB SERVER: ( the problem is one too many close parens ')' )

search_path = 'public'
14:01:44,307 DEBUG [syr/lloyd/9333C6.W01] AvailabilityDAOSql: SELECT date,
enddate, status, threshdesc, pollgrpid, pollid, REPLACE(polldata,'dhct:','')

poll USING (pollid) WHERE (status != 3) AND (lower(threshdesc) !~ 'dropped')
AND pollid IN (SELECT pollid FROM poll WHERE (rrdtypeid = 73) AND
(split_part(polldata,':',2)='IR')) AND (dsnum=2)) AND ((enddate >

status DESC

WEB QUERY IN PSQL:

ORDER BY date, status DESC;
ERROR: syntax error at or near ")" at character 366

We have found our issue, but it would have been nice to have had an error.
Could be we just need to be more conservative in our use of parens with
jdbc.

Thanks,
Woody
