在 Jboss Fuse 6.2.1（Fabric Managed）中安装 hazelcast 3.6.5 时出现问题

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。安装后它会抛出以下错误。

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，但出现以下错误“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（独立版和结构版）中运行良好。

Answer 1

您需要在 jboss 中激活对 sun.misc.Unsafe 包的访问权限。通常 OSGi 框架有一些配置，您可以在其中启用来自系统 classloader 的包到包中（引导 class 委派）。虽然不确定它在 fabric8 中究竟如何工作，但这个较旧的 post 过去修复过它，猜测配置仍然相同：https://developer.jboss.org/message/884503#884503

Answer 2

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

后来发现属性中还有一个名为“org.osgi.framework.system.packages.extra”的 /etc/custom.properties 文件，将 sun.misc 包添加到 /etc/custom.properties 文件解决了这个问题。

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