Intellisense breaks for JDK types when certain (scala) libs are on the classpath

When triggering autocomplete (ctrl+space) targeting JDK type java.lang.reflect.Field or java.util.List and certain (scala) libs are on the classpath, expected suggestions are not coming.

I've observed that List and Function are broken by the scala lib itself and Field is broken by Akka HTTP

Environment

• Operating System: Windows
• JDK version: 21.0.3 (Adoptium)
• Visual Studio Code version: 1.90.2
• Java extension version: 1.32.1

Steps To Reproduce

1. Attempt auto complete on variable type

Reproducer with dev container: https://github.com/spangaer/vscode-javals-completion-issue
(Dev container because SBT generated eclipse files, but my guess is that doesn't matter)

Current Result

Expected Result

Additional info

It looks to be really specific to the code completions. e.g creating a local var using Quick Fix... type inference does find the JDK types.

リンクされている dev-container reproducer から始め、Scala と Akka HTTP ライブラリを classpath に追加した状態で、java.lang.reflect.Field と java.util.List の補完を再現します。これらのライブラリがある場合とない場合の補完動作を比較します。期待される JDK 型の候補が表示され、Quick Fix の型推論が引き続き機能すれば完了です。
