    Sometimes occurring: DecoderException: org.infinispan.server.hotrod.HotRodException: java.lang.ClassCastException

      Hi~,

       

      Sometimes get operation occurring errors below.

      org.infinispan.client.hotrod.impl.protocol.Codec13 - ISPN004005: Error received from the server: io.netty.handler.codec.DecoderException: org.infinispan.server.hotrod.HotRodException: java.lang.ClassCastException

       

      Sample data is stored normally.

      But sometimes error occurred.

      And retry is successfully.

       

      I don't get it why it happens and what is the cause?

      Any help is greatly appreciated.

       

      Environments:

      JDK: jdk1.7.0_51

      Infinispan.version: 7.0.0.Alpha2

      Infinispan Server Hotrod cluster configuration.

       

       

      Exception:

      org.infinispan.client.hotrod.impl.protocol.Codec13 - ISPN004005: Error received from the server: io.netty.handler.codec.DecoderException: org.infinispan.server.hotrod.HotRodException: java.lang.ClassCastException

          Hi, we need the stack trace from server log to see where exactly this exception happened.

              Interesting, and really strange. Do you think you could reproduce that with TRACE logging level on org.infinispan? I am not sure how many servers do you use, but as I suspect there's some code path which is not executed very often (and that's why you get this exception only once in a while), this relates to distribution -> logs from all servers are needed to trace that down. And these will be huge - probably several hundreds MB, therefore, please upload them zipped to DropBox or similar place.
