    Unsupported key type: 'org.infinispan.util.ByteArrayKey'

    Jaya Prasad Rao Newbie

      Hi All,

       

      I tried to implement JdbcStringBasedCacheStore using oracle database.  Infinispan with hotrod start correctly with the following configuration.  When I tried to insert some values into cache I got the following exception.  Please advise on this. 

       

      Thanks in advance.
