    backward compatibility

    Mike Charnoky Newbie

      We are currently using HornetQ 2.2.5 and would like to upgrade to 2.2.18 to fix a number of bugs. However, I tried updating the client-side java libraries and now the client (2.2.18 libs) cannot connect to the existing HornetQ server (2.2.5). Does the HornetQ server side need to be upgraded first? I thought that with v2.2.0 things were backward compatible... Here is the error I am getting on the client side:
