持久化包只有在“Aries JPA容器”包更新后才会激活。

Question

问题是:我所有的持久性包都在ActiveGracePeriod之后失败，消息如下：

  | ERROR | rint Extender: 2 | BlueprintContainerImpl           | ntainer.BlueprintContainerImpl$1  332 | 8 - org.apache.aries.blueprint.core - 1.1.0 | Unable to start blueprint container for bundle com.*** due to unresolved dependencies [(&(&(org.apache.aries.jpa.proxy.factory=true)(osgi.unit.name=sessionunit))(objectClass=javax.persistence.EntityManagerFactory))]

如果我们刷新“白羊座JPA容器”包，而持久性捆绑包在GracePeriod中，那么所有GracePeriod都能正常工作。

的问题是:我们如何才能避免这种令人耳目一新的可笑？

谢谢。

升级到Karaf 2.3.3，因为旧版本包含了一个蓝图版本，确实产生了这种奇怪的效果。对于最新版本的Karaf (结合一个更新版本的Blueprint)，这不再是一个问题了。
