我有一个持久性捆绑包，大多数情况下它工作得很好，但每隔一段时间它就会卡在GracePeriod，当这种情况发生时，缺少的依赖是EntityManager：

karaf@root>bundle:diag 237
framework-connect-persistence (237)
 -----------------------------------
Status: GracePeriod
Blueprint
2/27/17 2:48 PM
Missing dependencies:
(&(osgi.unit.name=PersistenceUnitPrimary)(objectClass=javax.persistence.EntityManager))

但是，正如你所看到的，有一个EntityManager

karaf@root>service:list EntityManager
[javax.persistence.EntityManager]
 ---------------------------------
osgi.unit.name = PersistenceUnitPrimary
service.bundleid = 237
service.id = 427
service.scope = singleton
Provided by :
framework-connect-persistence (237)

重新启动捆绑包不会改变任何东西。但是重新启动捆绑包org.apache.aries.jpa.blueprint可以解决问题

有任何想法吗 ？

谢谢
