Eclipse工作台關閉時發生NullPointerException

Question

我正在使用BOJI（Junit）運行一些自動化測試，當測試完全運行並嘗試關閉工作台時，出現以下錯誤

!ENTRY org.eclipse.ui 4 0 2017-04-25 14:10:23.021

這與此處報告的錯誤完全相同

他們提到了該線程中的一些修復程序，但我沒有得到

任何人都遇到過同樣的問題，解決方案是什么？

Answer 1

SaveManager在工作空間上調用該方法以關閉並跟蹤，表明工作空間沒有被正常關閉。

可能是因為在測試中，它們可能鎖定了由上述線程鏈進一步調用的任何資源。

沒有代碼，因此我們不能多說。
