诊断从Karaf 3.0.1移植到4.2.5的问题

Question

我曾经使用Karaf 3.0.1处理旧版服务。从那以后，我搬到了同一组织中的另一个项目，但是原始团队现在需要升级到Karaf 4.2.5，并且他们在启动Karaf时遇到了麻烦。我认为这是其中一个功能文件中的缺陷，但我不了解所有细节。

在启动时，他们看到以下内容：

2019-05-15T21:45:36,871 | INFO  | activator-1-thread-2 | Activator                        | 12 - org.apache.karaf.deployer.features - 4.2.5 | Deployment finished. Registering FeatureDeploymentListener
2019-05-15T21:45:36,885 | ERROR | activator-1-thread-2 | FeatureDeploymentListener        | 12 - org.apache.karaf.deployer.features - 4.2.5 | Unable to update deployed features for bundle: org.apache.felix.framework - 5.6.12
java.lang.NullPointerException: null
    at org.apache.karaf.deployer.features.FeatureDeploymentListener.bundleChanged(FeatureDeploymentListener.java:247) [12:org.apache.karaf.deployer.features:4.2.5]
    at org.apache.karaf.deployer.features.FeatureDeploymentListener.init(FeatureDeploymentListener.java:95) [12:org.apache.karaf.deployer.features:4.2.5]

我检查了该版本的源代码，从堆栈跟踪中可以看出，该代码将NPE放在此块的“ removeAll”行上：

        Map<String, Set<String>> requirements = featuresService.listRequirements();
        requirements.get(ROOT_REGION).removeAll(reqsToRemove);
        requirements.get(ROOT_REGION).addAll(reqsToAdd);

我可以在此处提供功能部件文件，但是我不确定哪些功能适用，因此我将提供所有可能相关的所有三个功能：
