Add a setting to suppress the “Old Java Runtime” warning

Feature Request: Option to suppress the "Old Java Runtime" warning

I am using the Project Manager for Java extension in VS Code, and I frequently work with older JDK versions intentionally (for example, maintaining legacy applications or matching production environments).

Currently, the extension displays a popup warning every time a workspace opens:

"This project is using an older Java runtime…"

This popup cannot be disabled, and it appears even when the older JDK is intentionally used. This becomes disruptive when switching between multiple projects or reopening the editor.

Request

Please add a setting such as:

"java.runtime.ignoreVersionWarning": true

or any equivalent option that allows users to suppress this warning permanently.

Why this matters

• Many developers maintain legacy Java applications.
• Some teams must use older JDKs due to production constraints.
• The popup appears repeatedly and interrupts workflow.
• Other VS Code extensions allow disabling similar warnings.

This small setting would greatly improve usability for developers who intentionally use older Java versions.

Thank you for considering this request!

この issue では、具体的なファイルやテストは指定されていません。まず「Old Java Runtime」ポップアップの実装と、拡張機能に既存の設定登録を見つけ、次に提案されているオプトアウト動作のテストカバレッジを追加してください。新しい設定が有効になった場合に警告が抑制される一方で、デフォルトでは引き続き利用可能であれば完了です。
