描述
When Instances are created under sealed interface the Go To navigation does not work.
Environment
- Operating System:
- JDK version:
- Visual Studio Code version:
- Java extension version:
Steps To Reproduce
- Clone https://github.com/nipafx/nox.zone
- Import into VSCode
- Open HtmlElement.java
- Try to naviagate to Anchor class at 28 line with CTRL + Left Click, you can try any class from 28 line to 55.
Also, the same behaviour is present in ListItem.java class when the CTRL + Left Click is executed at 17 line on ListItem, or any of the input params of the methods.
In the screenshot below, the references are only loaded for constructor but not for the methods.
Screenshoot for ListItem

调研方向
按照列出的 CTRL+Left Click 步骤复现 HtmlElement.java 和 ListItem.java 中的故障，然后检查服务器日志中的 textDocument/definition 和 hover 错误。确认在 sealed interfaces 下，类和方法参数的导航可以正常工作，并且请求不再因 NullPointerException 而失败。
由索引模型根据 Issue 内容生成。
