CLONE - No Dialect mapping for JDBC type: 1188753216 in Wildfly (AttributeConverter and Byte)

I use AttributeConverter(

Open

) to convert enum value(

Open

). It run perfect normal when use "Persistence.createEntityManagerFactory(PERSISTENCE_UNIT_NAME)"(

Open

) to initialize the JPA runtime. But when I deploy it into WildFly as a EJB(

Open

), the JPA runtime initialization failed with the following exception:

In the Full log of Wildfly:

, i notice the following infomation:

2017-11-22 15:02:25,396 DEBUG [org.hibernate.cfg.annotations.SimpleValueBinder] (ServerService Thread Pool – 13) Starting fillSimpleValue for connectionState

When I refactor my code ConnectionStateConverter with the new one:
public class ConnectionStateConverter implements AttributeConverter<ConnectionState, Integer>, everything goes ok.

Why?
