Question

我安装了Eclipse Juno和IBM Worklight studio插件v5.0.5。特别支持eclipse Juno的worklight文档，但是如果我创建一个worklight项目然后关闭eclipse，然后尝试重新启动它，那么一个线程会在启动时挂起来从com.worklight.studio.plugin加载东西，我最终得到了杀死eclipse，因为它只是挂在加载屏幕上。它不是挂起的每次加载的包，它似乎是随机的。这是一次发生时的堆栈跟踪：

!MESSAGE While loading class "com.worklight.studio.plugin.classpaths.ServerAPIContainer", thread "Thread[org.eclipse.wst.sse.ui.internal.reconcile.StructuredRegionProcessor,1,main]" timed out waiting (5000ms) for thread "Thread[Worker-0,5,main]" to finish starting bundle "com.worklight.studio.plugin_5.0.5.20121129-1027 [882]". To avoid deadlock, thread "Thread[org.eclipse.wst.sse.ui.internal.reconcile.StructuredRegionProcessor,1,main]" is proceeding but "com.worklight.studio.plugin.classpaths.ServerAPIContainer" may not be fully initialized.

这是一个非常长的堆栈跟踪，所以我只是包含了我认为与之相关的部分。我可以通过从我的工作区中删除worklight项目来再次启动eclipse，但这意味着我只能在单个会话的项目上工作。我已经看过关于这个问题的其他帖子，但他们都给出了删除项目的相同解决方案。对这个问题有没有更持久的解决方案？

谢谢，亚历

卸载它并尝试最新版本5.0.6.1，但是也要确保从Eclipse工作区中删除WorklightServerHome文件夹（由于5.0.5和5.0.6.x之间的架构更改）。

com.worklight.studio.plugin线程在eclipse启动时挂起，如果现有的worklight项目在工作区中
