直到几天前，我在 Windows 10 下使用 Eclipse 2020-12 和 OpenJDK 14 都没有问题，现在我无法打开或使用任何使用 JDI 的功能ClassNotFoundException（即：设置运行配置、启动服务器、打开调试首选项， ETC）。
我不记得什么都没做，并确保我已经使用全新的工作区进行了全新安装：第一次运行后，保持 eclipse 不变，问题再次出现：只需打开 eclipse，转到 java 调试首选项，关闭eclipse，重新打开它并做同样的事情会触发错误。
这是异常堆栈跟踪：

并且有会话数据：
eclipse.buildId=4.18.0.I20201202-1800
java.version=14.0.1
java.vendor=AdoptOpenJDK
BootLoader constants: OS=win32, ARCH=x86_64, WS=win32, NL=es_UY
Framework arguments: -product org.eclipse.epp.package.jee.product
Command-line arguments: -os win32 -ws win32 -arch x86_64 -product org.eclipse.epp.package.jee.product
在我看来，org.eclipse.jdt.debug 版本 3.17.0.v20201117-1145 和 JDK 之间存在某种不兼容。我将做进一步的测试，但如果有人能指出我的解决方案，我将不胜感激。
我应该打开一个错误吗？
更新：使用 OpenJDK 15 解决了这个问题，所以它绝对介于最新的 Eclipse 和 OpenJDK 14 之间。
