             Summary: Missing transcoder for user marshaller's media type
                 Key: ISPN-11898
                 URL: https://issues.redhat.com/browse/ISPN-11898
             Project: Infinispan
          Issue Type: Bug
          Components: Core
    Affects Versions: 11.0.0.Dev05
            Reporter: Dan Berindei
            Assignee: Dan Berindei
             Fix For: 11.0.0.CR1


When the user configures a custom marshaller like {{JavaSerializationMarshaller}}, the cache needs a transcoder to wrap the user marshaller and convert between Java objects and the storage media type. Of course, if the cache's storage media type is not the same as the user marshaller's media type, another transcoder will be used, but the user marshaller transcoder needs to be available.

Currently {{EncoderRegistryFactory}} registers a transcoder wrapping the global marshaller instead, and the cache won't start:

{code:java}
      GlobalConfigurationBuilder gcb = new GlobalConfigurationBuilder();
      gcb.serialization().marshaller(new JavaSerializationMarshaller());
      DefaultCacheManager manager = new DefaultCacheManager(gcb.build());

      ConfigurationBuilder builder = new ConfigurationBuilder();
      builder.encoding().mediaType(MediaType.APPLICATION_SERIALIZED_OBJECT_TYPE);
      manager.createCache("cache", builder.build());
{code}
