我正试图在OSGi(bndtools/eclipse)下运行vertx，并从底层Netty获得此错误消息。
我使用的是vertx 3.3.3在独立模式下使用bndtools(maven)，因此所有依赖项都是使用maven导入的，而不是使用标准的bndtool(cnf)模板。

! Failed to start bundle mybundle.vertx-2.0.0, exception activator error Could not initialize class io.netty.util.internal.PlatformDependent0 from: io.netty.util.internal.PlatformDependent:<clinit>#101
在我的bundle activator中，我尝试使用静态方法创建一个新的vertx：
```
@Override
public void start(BundleContext bc) throws Exception {
Vertx vertx = Vertx.vertx();
```
在标准的bndtools模板(none-maven)中，这可以很好地工作。我不确定我能否在同一个项目中混合这两种模式，我更喜欢坚持maven格式。

我创建了这个从主要Paremus项目hello示例克隆而来的示例项目，以演示我在Vert.x&OSGihttps://github.com/gadieichhorn/hello-examples/tree/hello-1.13.x
编辑2
我将Vertx初始化移到了一个服务(而不是捆绑激活器)，现在我得到了一个更详细的错误。

感谢的任何帮助
这是因为"PlatformDependent0"导入了"sun.misc".
您可以通过设置"org.osgi.framework.system.packages.extra=sun.misc"来解决此问题
编辑1:
我以这种方式启动OSGi框架(ApacheFelix)：
Map<String, String> configProperties = Main.loadConfigProperties();
Main.copySystemProperties(configProperties);
configProperties.put("org.osgi.framework.system.packages.extra","sun.misc");
Framework fw = new Felix(configProperties);
fw.init();
AutoProcessor.process(configProperties, fw.getBundleContext());
但我想你可以直接把这个设置放在"felix.config.properties"文件中。
由于sun.misc是专用API，因此出现了问题。因此，您必须明确地将包添加为主捆绑包提供的额外包。它是为公共API(java.lang，java.util…)隐式完成的
