我已经被这个卡住了一段时间了。我已经创建了发生这种情况的项目的一个迷你子集并重现了该问题。基本上我正在运行一个测试，它将带有一个 bean 的 spring 上下文文件加载到 ClassPathXmlApplicationContext 对象中。

奇怪的是，在 Windows 上，当我从 IDE（Eclipse/Intellij）运行时以及通过 maven 命令行运行时，我的测试通过了。在 UNIX 机器（Red Hat Enterprise Linux 5）上运行测试时，它会失败（这是代码不可避免地结束的地方）。

在下面的异常中，它抱怨 LookUtils 类。我不明白它为什么要创建这个类，但我注意到它有一个私有构造函数。另外，我正在使用 spring v2.5.6 并且出于安全原因必须坚持使用它。我非常坚持这个，所以任何帮助将不胜感激。

谢谢你。

这是我的测试：

package StartupTest;

import org.junit.Test;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class AppTest {
    @Test
    public void testGuiStartup() {
        new ClassPathXmlApplicationContext("startup-context.xml");
    }
}

这是我的上下文文件：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN"
        "http://www.springframework.org/dtd/spring-beans.dtd">

            <bean class="com.jgoodies.looks.plastic.theme.ExperienceRoyale"/>

终于想通了。毕竟很简单。所以它在 UNIX（Red Hat Enterprise Linux 5）上失败的原因是因为这台机器上没有图形界面！没有 Gnome，没有 KDE 或任何东西。因此，它在尝试配置应用程序 GUI 的外观和感觉时失败了。事后看来，我应该提到我正在使用 TeamCity 来运行这些测试，而且我从来没有在 RHEL5 服务器前面。

解决方案是创建一个仅运行 GUI 测试的新 TeamCity 构建，并在 Windows 机器上执行此操作。

故事的寓意是，如果在远程机器上运行 GUI 测试，请确保它具有图形支持！
