Eclipse:在方法上移动鼠标时引发SSLException

我使用的是Eclipse.3a版本（4.7.3a）。当我打开任何Java文件，并将鼠标光标移到某个方法上时，错误日志中将抛出以下异常。这让我非常困惑，因为我没有做任何涉及连接的事情，比如更新软件。有什么问题吗

从方法名称来看，编辑器似乎正在尝试获取Javadoc，以便在悬停弹出窗口中显示。您的操作系统和Java版本是否与您的Eclipse版本一样新？是否有尚未应用的根证书更新？我的Java版本是8。Eclipse版本是最新的。Javadoc hover从未对我起过作用，即使是在我使用早期版本的Eclipse时（我认为早期版本中没有SSLException）。为什么我在使用笔记本电脑时需要关心根证书？我该如何解决这个问题呢？使用笔记本电脑与任何事情都无关。Java运行时的代码中发生了异常。谷歌搜索错误消息可能会导致您在这里遇到类似的问题，但我建议在强制执行任何操作之前应用所有Java和操作系统更新。
