Eclipse Helios - “java.lang.RuntimeException：Widget 处置得太早！”

Question

你好 我在 Win XP 上运行 Eclipse Helios。
今天启动时，收到一条消息，告诉我 Eclipse 无法启动。

以下是生成的日志文件的内容：

知道如何解决吗？

Answer 1

XUL Runner 运行时环境版本高于 1.9.0.x 时会出现此问题，例如版本 1.9.1。

您可以通过运行以下命令来确定 XUL Runner 运行时环境的配置版本：

xulrunner -v

编辑 eclipse.ini 文件。
找到 -vmargs 行并添加新行以使用以下语法指定 XUL Runner 运行时环境的版本：

-Dorg.eclipse.swt.browser.XULRunnerPath=/usr/lib/xulrunner-1.9.x.x

Answer 2

对我来说，增加 --launcher.XXMaxPermSize
eclipse.ini 中的 256m 到 512m 有效。
一旦 Eclipse 加载了许多插件和功能，就会出现此问题，因为 Eclipse 在启动期间加载这些新插件/功能时需要额外的空间。

Answer 3

报告此类消息的所有错误（例如 bug 260772 或 < a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=239681#c9" rel="nofollow noreferrer">bug 239681）提及XulRunner：您最近不会安装它吗？

Eclipse/SWT 3.4 支持任何
mozilla/seamonkey/xulrunner/firefox-iff-dynamically-linked >= mozilla 1.4。

从 FireFox3 开始，FireFox 附带了一个专用的 xulrunner 供其使用，但这不是一个完整的安装，浏览器可以独立于它附带的 FireFox 来指向。
但是，如果 FireFox 是动态链接的，那么浏览器就可以使用它（FireFox），并且 FireFox 使用私有 xulrunner 来完成其工作这一事实只是一个例子。
浏览器不知道/关心的实现细节。

如果您安装了 xulrunner 1.9~b5+nobinonly-0ubuntu3 - 那么 Eclipse 3.4 不起作用 - 并且您安装或卸载哪个版本的 FireFox 似乎并不重要

---

另一个原因与某些工作区损坏有关，这可能会解释为什么OP balderman 评论：

我找到了一种通过注释掉以下行来启动 Eclipse 的方法：RECENT_WORKSPACES=bla bla 在文件 org.eclipse.ui.ide.prefs 中：作为问题“如何删除 RAD 中过时的工作区？"，这实际上不会删除工作区，但允许跳过可能存在某种损坏问题的工作区。

Answer 4

你是否得到：

org.eclipse.swt.SWTError: No more handles

每次开始时？
这意味着 Eclipse 操作系统资源不足，您是否还打开了许多其他应用程序？尝试关闭您正在运行的一些其他应用程序。

如果您没有运行许多其他应用程序，您可能需要考虑查看 sleak，这是一个监视 eclipse 和 eclipse RCP 句柄使用情况的 eclipse 插件。

您运行的是普通 Eclipse，还是安装了许多插件？如果普通 Eclipse 耗尽了句柄，我会感到非常惊讶......这更有可能是由插件引起的（无论如何，根据我的经验）。

Answer 5

1. 备份“..\.metadata.plugins\org.eclipse.core.resources” forler
2. 空“..\.metadata.plugins\org.eclipse.core.resources\.safetable\org.eclipse.core.resources”文件
3. 运行弹性。您的项目列表将为空
4. 关闭 Flex
5. 恢复“..\.metadata.plugins\org.eclipse.core.resources”文件夹（覆盖全部）
6. 运行 Flex。
