Handling DatabaseException, OperationStatus.KEYEXIST, from Secondary Db

Question

Hi,
If I insert a record into my primary db I might do something like:
OperationStatus status = db.put(null, key, data);
if (OperationStatus.SUCCESS != status) {
// handle                    
However, if I have a also have a secondary database, and if the put operation above were to result in a duplicate key on the secondary database then a DatabaseException is thrown:
Exception in thread "main" com.sleepycat.je.DatabaseException: (JE 3.3.82) Could not insert secondary key in SecDb OperationStatus.KEYEXIST
My question is how can I handle this exception gracefully, and test for the OperationStatus from the secondary db insert? I could catch it:
               OperationStatus status = null;
               try {
                    status = db.put(null, key, data);
                    if (OperationStatus.SUCCESS != status) {
                         // X: handle primary db error
               } catch (DatabaseException e) {
                    if (OperationStatus.KEYEXIST == status) {
                         // Y: handle secondary db duplicate record
                    } else
                         throw e;
But status is always null, and does not reflect the OperationStatus code from the secondary db put operation, so the line X above never triggers. Is there another method I should be using to test for failed inserts on a secondary database due to duplicate keys?
Thanks,
Joel

Joel,
In the newest release, JE 4.0, we attempted to help with this problem by expanding the set of exception classes. In this case, you should get a UniqueConstraintException, which is a subclass of DatabaseException. See http://www.oracle.com/technology/documentation/berkeley-db/je/java/com/sleepycat/je/UniqueConstraintException.html.
