java.lang.NoClassDefFoundError: Could not initialize class java.awt.Toolkit
提问by Bertram Nudelbach
I'm working on XUbuntu 13.04 and developing swing applications. As I just wanted to try that application I ran into java.lang.NoClassDefFoundError: Could not initialize class java.awt.Toolkiton startup.
我正在使用 XUbuntu 13.04 并开发 Swing 应用程序。因为我只是想尝试那个应用程序，所以我java.lang.NoClassDefFoundError: Could not initialize class java.awt.Toolkit在启动时遇到了。
I've found several questions about server/client vms and noticed that I have a server VM and that for Linux 64 there is no client VM anymore. But nevertheless IMHO this problem shouldn't depend on which VM I'm running on.
我发现了几个关于服务器/客户端虚拟机的问题，并注意到我有一个服务器虚拟机，而对于 Linux 64，不再有客户端虚拟机。但是恕我直言，这个问题不应该取决于我正在运行的 VM。
Has anybody else noticed that problem and has solved it? What am I doing wrong? With 64bit jdk everything works fine, but when I try to use the 32bit jdk the startup fails.
有没有其他人注意到这个问题并解决了它？我究竟做错了什么？使用 64 位 jdk 一切正常，但是当我尝试使用 32 位 jdk 时，启动失败。
Thanks in advance!
提前致谢！
P.S.: Java version is 1.7.0_25and same with 1.7.0_09
PS：Java 版本1.7.0_25与1.7.0_09

Okay, finally I've found the answer. Thanks for the effort! The problem is that I had libxtst6installed but only the 64bit-version of it.
好吧，我终于找到了答案。感谢您的努力！问题是我已经libxtst6安装了它的 64 位版本。
sudo apt-get install libxtst6:i386did the trick for me.
sudo apt-get install libxtst6:i386帮我解决了这个问题。
How did I find this answer? I ldded around a bit, but nothing, as you can see in the following:
我是如何找到这个答案的？我转ldd了一下，但没有，你可以在下面看到：

So that was the point when I ended trusting my IDE and started a sample application on the command line. And the command line again was nice to me:
所以这就是我结束信任我的 IDE 并在命令行上启动一个示例应用程序的时候。命令行再次对我很好：
