It does seem like maybe this should be the default. Although I think right now the way that it detects that it needs to clear the PDX types could be improved - I think it just looks to see if the client is no longer connected to any servers. Really, we should be detecting whether the servers have lost their PDX type registry on reconnect. As Anil pointed out, that should be a rare case of not having persistence on the server side or deleting all of the persistent files on the server side without restarting the clients. I guess that might be more common in a dev environment.
