    HotRod client 7.0.3 sending invalid 2.0 code when using "1.3" protocol version

    frank_s Newbie

      I am attempting to switch to Infinispan 7.0.3.  I have 3 Infinispan servers in a cluster supporting HotRod.

       

      My Java clients are using the latest 7.0.3 HotRod client library.  I was getting endless "ArrayIndexOutOfBounds" exceptions on the client side which appears to be a defect with the HotRod 2.0 protocol handling view changes, so I was trying to work around it by setting the protocol version to 1.3.

       

      I'm doing this with the ConfigurationBuilder to specify the version:

       

      cb.protocolVersion("1.3").


      I can see in the logs that it using Codec13.

       

      The problem is that one of my clients is calling "isEmpty" on the cache, and the HotRod library is using code 0x29 (41) which is a new code specific to HotRod 2.0.

       

      Here is some TRACE output from the HotRod client:

      So far, other operations seem to work fine using the "1.3" codec.

       

      As a sanity test, I switched the client lib back to 6.0.2, but left the server at 7.0.3, and that seems to be stable (so far...).

       

      Ideas?  Is this a defect?
