Eclipse Helios - 「java.lang.RuntimeException：Widget處理得太早！」

Question

嗨 我在Win XP上運行Eclipse Helios。
今天開始時，我收到一條消息，告知Eclipse無法啓動。

這裏是生成的日誌文件的內容：

Answer 1

所有的bug報告這類消息時（如bug 260772或bug 239681）提XulRunner：你不會最近安裝了嗎？

的Eclipse/SWT 3.4支持任何 Mozilla瀏覽器/設備SeaMonkey/xulrunner的/火狐-IFF-動態鏈接> = 1.4的Mozilla。

從FireFox3開始，一個私有的xulrunner隨FireFox一起發貨使用，但這不是一個完整的安裝，瀏覽器可以指向獨立於它的FireFox。
但是，如果FireFox是動態鏈接的，那麼瀏覽器可以使用它（FireFox），並且FireFox使用私有的xulrunner來完成它的工作的事實只是一個 實現細節，瀏覽器不會知道/關心。

如果您已經安裝xulrunner的1.9〜B5 + nobinonly-0ubuntu3 - 那麼Eclipse的3.4不起作用 - 這似乎並不重要，你安裝或卸載什麼版本的FireFox

---

另一個原因是相關的一些工作區的腐敗，這或許可以解釋爲什麼OP balderman評論：

我找到了一條通過註釋掉行啓動eclipse：RECENT_WORKSPACES=bla bla文件org.eclipse.ui.ide.prefs在：作爲問題「How to delete obsolete workspace in RAD?」，日在實際上並沒有刪除一個工作區，但允許跳過可能存在某種腐敗問題的工作區。

Answer 2

你明白：

org.eclipse.swt.SWTError: No more handles 

每次啓動？這意味着Eclipse將耗盡操作系統資源，您是否還有許多其他應用程序處於打開狀態？嘗試關閉一些其他正在運行的應用程序。

如果您沒有運行其他許多應用程序，您可能需要考慮查看sleak，監視器的eclipse插件處理eclipse和eclipse RCP的使用情況。

您是在運行純Eclipse還是安裝了許多插件？如果vanilla Eclipse用完了句柄，我會感到非常驚訝......它更可能是由插件引起的（無論如何，我的經驗）。

Answer 3

對我來說，增加--launcher.XXMaxPermSize 256m到512m在eclipse.ini工作。 一旦Eclipse加載了許多插件和功能，就會出現此問題，因爲在啓動過程中加載這些新插件/功能時，Eclipse需要額外的空間。

Answer 4

XUL Runner運行時環境版本晚於1.9.0.x，例如版本1.9.1，會出現此問題。

您可以通過運行以下命令確定XUL亞軍運行時環境的配置版本：

xulrunner -v 

編輯eclipse.ini文件。 找到-vmargs線，並添加一個新行使用此語法指定XUL亞軍運行時環境的版本：

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

Answer 5

1. 備份」 .. \ metadata.plugins \ org.eclipse.core.resources 「forler
2. 空」.. \。metadata.plugins \ org.eclipse.core.resources \ .safetable \ org.eclipse.core.resources「文件
3. 運行Flex。您的項目列表將是空
4. 密切的Flex
5. 恢復 「.. \。metadata.plugins \ org.eclipse.core.resources」 文件夾（覆蓋所有）
6. 運行的Flex。
