升级到karaf 4时出现错误sun.misc。来自karaf 3的x。X

Question

我们遇到了阻止我们的问题。我们在Apache karaf 3.0.3、地窖3.0.3中的项目运行良好。现在我们升级到Apache karaf 4.2.0和Apache地窖4.1.0。我看到了这个错误

[activator-1-thread-2]ERROR org . Apache . karaf . features . internal . service . bootfeaturesinstaller-安装引导功能时出错org . OSGi . service . resolver . resolution异常:无法解析根:缺少要求[root]OSGi . identity；osgi.identity = OUR _ FEATUREtype = karaf.feature版本="[18.12.4，18 . 12 . 4]"；过滤器:= "(

正如我们所看到的，错误来自com.hazelcast，版本3.8.1

事实上，在过去，我们使用karaf地窖和karaf 3.0.3，他们使用com.hazelcast/hazelcast/version3.4.2（https://mvnrepository.com/artifact/com.hazelcast/hazelcast/3.4.2）

现在有了karaf 4.2.0和cellar 4.1.0，他们使用com.hazelcast/hazelcast-all/3.8.1 https://mvn repository . com/artifact/com . hazel cast/hazel cast-all/3 . 8 . 1，这个版本导致了这个错误

这是我们的功能内容.xml文件

<repository>mvn:org.apache.karaf.cellar/apache-karaf-cellar/4.1.0/xml/features</repository>
<feature name="OUR_FEATURE" version="18.12.4" description="Our description">

    <feature version="${project.version}">other_features</feature>

我们尝试在安装后的目标目录中搜索（mvn干净安装）并在目标文件夹中找到这些功能

在我们的 src/main/distribution/etc/config.properties 中，我们已经遵循了 config：org.osgi.framework.system.packages.extra=sun.misc

org.osgi.framework.bootdelegation=org.apache.karaf.jaas.boot，org.apache.karaf.jaas.boot.principal，org.apache.karaf.management.boot，sun.，com.sun.，javax.transaction，javax.transaction.，javax.xml.crypto，javax.xml.crypto.

在我们的src/main/distribution/etc/custom . properties中，我们有以下配置:

karaf.systemBundlesStartLevel=50org.osgi.framework.system.packages.extra=org.apache.karaf.branding

请帮助我们解决这个问题。

谢谢

org.osgi.framework.system.packages.extra=sun.misc

Answer 2

当捆绑包加载类但不为它们定义导入包语句时，将使用引导委托。

在你的案例中，hazelcast有一份进口包裹声明。因此，要实现这一点，您必须从系统包中导出这个包。

要执行此操作，请编辑config.properties并将sun.misc添加到org.osgi.framework.system.packages.extra。
