我一直想在 Ubuntu 15.04 上运行 Minecraft。每次我尝试运行它时，它都不会下载启动器包，并显示以下消息：

（我不知道如何或者是否有可能剧透）
我手动下载了 launcher.pack，所以它进入启动器并显示登录屏幕，但随后它说无法访问 Mojang 服务器，我无法绕过它。我发现其他人也有同样的问题，他/她说当他从 OpenJDK 切换时，他/她的问题就解决了（我曾是使用 OpenJDK）到 Oracle Java（或者至少我尝试过。）我这样做了，但没有任何变化。当我使用java -version
*****@Desktop-Ubuntu:~/Software/Minecraft$ java -version
Picked up JAVA_TOOL_OPTIONS: -javaagent:/usr/share/java/jayatanaag.jar
