Question

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)"]]

尝试安装片段包以暴露sun.misc包但出现以下错误“错误：资源没有uri ”。

Fragment bundle：mvn：com.diffplug.osgi / com.diffplug.osgi.extension.sun.misc / 0.0.0

注意：同样的方法在Fuse 6.1.0版本（独立版和结构版）中都能正常工作。

Answer 1

您需要在jboss中激活对sun.misc.Unsafe包的访问权限。通常，OSGi框架具有一些配置，您可以在其中将软件包从系统类加载器启用到软件包（引导类委派）。虽然不知道它在fabric8中是如何工作的，但是这篇旧帖子在过去修复了它，猜测配置仍然是相同的：https://developer.jboss.org/message/884503#884503

Answer 2

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

后来发现在 / etc / custom中还有另一个名为“ org.osgi.framework.system.packages.extra ”的属性。属性文件，将sun.misc包添加到/etc/custom.properties文件修复了该问题。

# Branding
org.osgi.framework.system.packages.extra = org.apache.karaf.branding,com.sun.xml.bind.v2.model.core,sun.misc
