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
