Jsonb support for Hibernate in spring boot 2.0.1

[rtisma]

Using spring boot 2.0.1 and following the instructions in the read me, the following error occurs

java.lang.AbstractMethodError: com.marvinformatics.hibernate.json.JsonUserType.nullSafeSet(Ljava/sql/PreparedStatement;Ljava/lang/Object;ILorg/hibernate/engine/spi/SharedSessionContractImplementor;)V

	at org.hibernate.type.CustomType.nullSafeSet(CustomType.java:160)
	at org.hibernate.persister.entity.AbstractEntityPersister.dehydrate(AbstractEntityPersister.java:2715)
	at org.hibernate.persister.entity.AbstractEntityPersister.insert(AbstractEntityPersister.java:3009)

	at org.hibernate.engine.spi.ActionQueue.executeActions(ActionQueue.java:474)

The simple fix is to just overload with the missing methods

public class CustomJsonType extends JsonUserType {

  public Object nullSafeGet(ResultSet rs, String[] names, SharedSessionContractImplementor session, Object owner) throws HibernateException, SQLException {
    return nullSafeGet(rs, names, (SessionImplementor) session, owner);
  }

  public void nullSafeSet(PreparedStatement st, Object value, int index, SharedSessionContractImplementor session) throws HibernateException, SQLException {
    nullSafeSet(st, value, index, (SessionImplementor) session);
  }

}

version 4.0 depends on hibernate-core 4.2.21-Final, which does not have the SharedSessionContractImplementor class. Spring boot 2.0.1 uses hibernate-core 5.2.16-Final, and has this class

This may be a good time to move from hibernate 4 to 5.
