    Exception with NearCache in HotRod client accessing Embedded Infinispan server - 8.0.2 & 8.2.2

    Manjunath D Newbie

      Hi,

       

      I have a Java program that embeds a HotRod Infinispan server and the remote Java applications access the caches using the HotRod API. This perfectly works fine however when the NearCache is enabled at the client, the following exception is observed at the server.

       

      An example implementation is at https://gist.github.com/manjunathd/d01e53ecbfd00539cf5689bd3e6fb581

      I tried with 8.0.2 and 8.2.2 version of Infinispan.

       

      Can you please help me understand if I'm missing any configuration?

       

      Thank you.
