问题描述
昨天进行编码时，我偶然发现了Eclipse IDE中发生的突然错误。我想重命名一个变量，然后按ALT + SHIFT + R（按我的习惯），但是这在工具栏中打开了 Run 。我以为好吧，也许我按下了错误的键，但是这个错误不断发生。
然后我尝试重新启动Eclipse，重新加载项目（删除了该项目，但未删除磁盘上的内容，然后通过导入再次加载了该项目），还删除了工作区，但仍然发生错误。
然后我认为安装可能因某种原因而中断，所以我重新安装了Eclipse（顺便说一句，我使用的是最新的 06-2020 版本）。但这也没有帮助...
在大量使用Google之后，我还发现了以下文章，该问题似乎与
类似- Can't refactor rename in Eclipse
- Eclipse refactoring fails -> Keeps throwing exceptions!
- https://www.eclipse.org/forums/index.php/t/375178/
但是这些建议对我没有用。
浏览错误日志时看到的是，使用重命名功能时发生了很多错误。我希望有人对如何解决此问题提出建议，因为用鼠标重命名也不再起作用。
更多详细信息：
- 突然发生错误>它一直有效，突然停止工作，至少（至少我）不知道任何变化
- 我将Windows 10与OpenJ9 JDK14用作默认JDK和JRE，因此eclipse也使用此JRE
