High CPU Usage

Potentially related issues:

• https://github.com/redhat-developer/vscode-java/issues/2734
• https://github.com/redhat-developer/vscode-java/issues/3387

This extension destroys my cpu usage and all the recommendations in those two threads have failed.

My setup:

• VS Code Remote extension
• AL2 instance
• RedHat version v1.36.0

The command of the largest process is:

Happy to provide more info on request

関連する issue 2734 と 3387 から始め、Red Hat extension v1.36.0 を使用して AL2 インスタンス上の VS Code Remote で報告された高い CPU 使用率を再現します。レポートに示されている Java/JDT language-server プロセスをプロファイリングします。過剰な CPU 使用率の原因が理解されて対処されるか、必要な診断エビデンスが文書化された時点で issue は完了です。
