如何修复Eclipse Debug Hang

Question

我正在运行Ubuntu 10.04 LTS和Eclipse版本：Helios Service Release 2 构建id：20110218-091，调试PHP。虽然每次都没有发生，但在我完成调试后，当我点击红色方块停止进程时，Eclipse屏幕变灰，然后停留在那里。顶部或系统监视器显示Eclipse正在使用剩余的CPU周期，在我的情况下，它在67-85％之间。它会保持这种状态，直到我杀死这个过程（我等了10分钟或更长时间）。日志中的最后一个错误是： 插件net.sf.simpletest.eclipse无法加载类net.sf.simpletest.eclipse.launcher.SimpletestLaunchShortcut.Plug-in net.sf.simpletest.eclipse was unable to load class net.sf.simpletest.eclipse.launcher.SimpletestLaunchShortcut.

这刚刚开始发生，所以我倾向于认为我的机器有什么问题，来自Ubuntu的更新，内存???

Eclipse事件详细信息的输出如下。

欢迎任何建议。

Answer 1

原因很清楚。初始化类时抛出异常，这是由在非UI线程中访问SWT Display引起的。
