Well, this won't work for me since I'm trying to relogon to a previous
session. This means that my counterparty are expecting a certain
seqnum for the session and if I remove the .seqnums file I will try to
logon with seqnum =3D 1 which isn't going to work.

No, this is not a solution for me either.

Since you've had the same problem I guess this makes the problem a bug
in QuickFIX/J so I'll report this as a bug.

Thanks,
