説明
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

コントリビューションガイド
はじめの一歩
- issue を最後まで読み、次にプロジェクトのコントリビューションガイドを読みます。
- 着手することを issue にコメントします — 二人が同じ作業をするのを防げます。
- リポジトリをフォークし、ブランチを切って変更します。
- issue 番号を参照したプルリクエストを送ります。
調査の方向性
記載されているCTRL+Left Clickの手順でHtmlElement.javaとListItem.javaの失敗を再現し、その後、サーバーログでtextDocument/definitionとhoverのエラーを調査してください。sealed interfacesでクラスとメソッドパラメーターのナビゲーションが機能し、リクエストがNullPointerExceptionで失敗しなくなったことを確認してください。
