    ClassCast Exception while state transfer

    Sayaji Patil Newbie

      Hi Guys

       

      We are struggling for couple of days with this hairy issue. We have a two node cluster where when one of them tries to get the state from the other one while restart failing because of the following exception. We are using inifinispan version 4.2.1 FINAL. Is it a known problem? Or am I missing any configuration?

       

      Please help....
