我正在尝试在 Jboss Fuse 6.2.1 服务器（Fabric Managed）中安装 hazelcast-all-3.6.5 版本。安装后会抛出以下错误。

Unable to update agent org.osgi.service.resolver.ResolutionException: Unable to resolve root: missing requirement [root] 
osgi.identity; osgi.identity=appid1-hazelcast; type=karaf.feature; version=0 
    [caused by: Unable to resolve appid1-hazelcast/3.0.1.release: missing requirement [appid1-hazelcast/3.0.1.release] 
osgi.identity; osgi.identity=com.hazelcast; type=osgi.bundle; version="[3.6.5,3.6.5]"; resolution:=mandatory 
    [caused by: Unable to resolve com.hazelcast/3.6.5: missing requirement [com.hazelcast/3.6.5] 
osgi.wiring.package; filter:="(osgi.wiring.package=sun.misc)"]]

尝试安装片段包以公开 sun.misc 包，但收到以下错误“错误：资源没有 uri ”。

片段包：mvn:com.diffplug.osgi/com.diffplug.osgi.extension.sun.misc/0.0.0

注意：相同的方法在 Fuse 6.1.0 版本（独立和结构）中运行良好。

您需要sun.misc.Unsafe在 jboss 中激活对包的访问权限。通常，OSGi 框架有一些配置，您可以在其中启用系统类加载器中的包到包中（引导类委托）。不知道它在fabric8中究竟是如何工作的，但这个较旧的帖子在过去修复了它，猜测配置仍然相同：https ://developer.jboss.org/message/884503#884503

最初我已将sun.misc包附加到etc/config.properties文件中的“ org.osgi.framework.system.packages.extra ”属性，但这并没有解决问题。（这应该适用于 90% 的情况）。

后来发现/etc/custom.properties文件中存在另一个名为“ org.osgi.framework.system.packages.extra ”的属性，将 sun.misc 包添加到 /etc/custom.properties 文件解决了这个问题。
