Eclipse 在显示悬停建议时冻结，例如 class 中的方法建议、方法信息等

Question

当我在输入 class 名称后输入点运算符时，Eclipse 将显示方法建议自动完成，此时 Eclipse 挂起并自动关闭。

显示方法信息时也会出现这种情况。有人可以帮忙吗？

当我检查 Eclipse 日志时，我看到了这些异常

感谢@greg-449 的评论。

The errors say that you have installed a plug-in which requires at least Java 11 but you are using Java 8 on Eclipse 2019-09 (4.13) which is now 3 years and 10 releases old. Try running on the current Eclipse 2022-03 (4.23).

卸载插件后解决，至少需要Java11
