Use separate output channels for language server and extension

When I start a Java project, there are two output channels created:

1. "Language Support for Java"
2. "Language Support for Java (Syntax Server)

They both seem to collect output from whichever language server the extension starts. Since we can either have the "syntax server" or the "standard server" running, I'm not quite sure what we have two different channels. If we're mixing output from the extension itself with the output from the language server, I would not expect two different channels. If we have a separate channel for the extensions, I would expect only the relevant language server output channel to be created.

まず、拡張機能が "Language Support for Java" と "Language Support for Java (Syntax Server)" の出力チャネルを作成している場所を特定し、標準サーバーと構文サーバーの起動パスを比較します。拡張機能の出力が適切に分離され、関連する language server のチャネルだけが作成されれば完了です。それぞれのサーバーで Java プロジェクトを起動したときの動作を確認してください。
