 以前從沒遇到過這種問題,發現自重裝系統後,就開始觸發這個bug了.

從error-log等視圖裡點擊開啟的java檔案或者xml檔案時,出現”unhandled event loop exception”錯誤,出錯資訊如下:

我的解決過程:網上搜尋後找到這個.

解決方案: 重裝了下jdk(沒有重啟機器)還是無效.然後,修改了workspace,重啟機器,ok.發現,很多問題都可以通過修改workspace來解決,建議一個工程一個workspace. 上述方法無效！！ Google下發現好像是開啟.java的預設編輯器在win7x64位的筆記本上有問題，解決方案：help->install new software，從http://download.eclipse.org/windowbuilder/WB/release/R201309271200/4.3下載windowbuilder，並把其設定為預設的.java編輯器。重啟Eclipse後切換回.java檔案時不出bug了,但是切換回.xml檔案還是會觸發這個bug。

最後的終極解決方案:更新 Win7 ! ok,問題解決!

(windows update了下win7,搞定！！所以：直接進行windows update，安裝關於security的補丁！)
