Camel JPA 幂等性 + OSGI (Jboss Fuse)

Question

当我尝试在 Fuse Fabric OSGI 容器（fuse-karaf 6.3）中使用 JPA 幂等时遇到问题。 我得到了这个例外：

Caused by: java.lang.ClassNotFoundException: org.hibernate.proxy.HibernateProxy not found by org.apache.camel.camel-jpa [121] 

我用示例创建了一个简单的项目：camel-jpa-idempotent

这是我的路线：

from("jpa:com.mycompany.model.Client?persistenceUnit=persistenceUnit&consumeDelete=false") 
                .split().simple("${body}") 
                        .idempotentConsumer(simple("${body.id}/${body.name}"), JpaMessageIdRepository.jpaMessageIdRepository("persistenceUnit", "ClientRepository")) 
                        .log("${body.name} processed");

Bug 确认并解决

该问题在 Fuse 6.3 中被确认为 Bug 并已解决 here，因此我更改为使用 camel-jdbc 的幂等性。
