我试图运行使用Equinox in Neon的Eclipse 3.x应用程序，如在this question中启动的那样。ExtendedLogService似乎并未启动
看来，我剩下的问题是，LogReaderService似乎不可用，如org.eclipse.core.internal.runtime.InternalPlatform.getLog（下面第二行）似乎抛出NullPointerException异常：
ExtendedLogReaderService logReader = logReaderTracker.getService();
logReader.addLogListener(result, result);
此类的实现可以在org.eclipse.osgi，这我启动与应用程序被发现。但是，无论出于何种原因，该服务都是空的，这会导致大量插件在记录时引发异常，因为许多插件依赖于从Activator获取记录服务。
由于org.eclipse.osgi包含在其内部的实现，我假定它也会注册该服务。这似乎并非如此。我也尝试过，包括log4j和org.apache.felix.log并且都不会解决此问题。
必须有一些简单的东西，在这里失踪让LogService开始？这里的堆栈跟踪：

我还添加了
Require-Capability: osgi.service;filter:="(objectClass=org.osgi.service.log.LogService)";effective:=active
要依赖BND文件之一。这似乎没有解决问题。
编辑：因为OSGi框架在 bndrun文件设置为 org.eclipse.osgi，是防止日志得到初始化？我也尝试加入 org.apache.commons.logging以及 osgi.enroute.equinox.log.adapter当我有任何尝试登录时，我仍然会收到NPE。在RCP插件被激活时， org.eclipse.osgi包已经被认为运行了......但是没有 ExtendedLogReaderService。我是否需要找到一种安装Felix作为Core Runtime的方法，以使 org.eclipse.osgi能够由框架启动，以使 ExtendedLogReaderServiceImpl得到注册？
我发现了很多关于如何监听LogService的例子......我看不到如何启动ExtendedLogService。
编辑2：我可以通过注册虚拟
ExtendedLogService实现来抑制
LogService空值问题。
