vscode-java causes vscode to stop responding

I don't understand why this hasn't been reported since the issue has been present in the insiders version since the week before Christmas. I'm going to blame the bystander effect for that.

[provide a description of the issue]
Using vscode and the vscode-java extension to edit java files causes vscode to stop responding. It appears to be related to whatever the fix was for #1597 as vscode seems to stop responding exactly when the highlighting used to break.

Environment

• Operating System: Microsoft Windows [Version 10.0.21322.1000] (This occurs on the latest non-insiders windows version as well)
• JDK version: 15.0.2
• Visual Studio Code version: 1.54.1
• Java extension version: v0.76.0

Steps To Reproduce

1. Open a Java project
2. Open a Java file
3. Start writing some java code

I understand that this is a large project to be a sample but I know for certain it occurs with this project. https://github.com/astrelsky/Ghidra-Cpp-Class-Analyzer

Current Result

Vscode stops responding when using vscode-java.

Expected Result

The vscode-java extension should not cause vscode to stop responding.
