HotRod client try to unmarhall an object on get() no matter whether the put() use a byte[] or not

      • Client serialize the object and do a put(key, byte[]).
      • as long as the class is available the get return the class (MyValue)
      • if the class is renamed after write the byte[] is returned

      project can be run by
      java -cp target/HotRodSimpleRemoteClient-1.0.jar:$ISPN_LIBS/infinispan-remote-8.0.1.Final.jar infinispan-remote-8.0.1.Final.jar com.bankia.TestMarshall.TestCache

      If a client put an object as byte[] into the cache, which is a self serialized class, the get will return the original class (if it is in the class path) instead of the byte[].
      This is incompatible to ISPN5 here the byte[] is returned in any case.

      It seems this in unintentional due to the smart 'compatibility' mode at client side

      The client should be able to get the same class type back
