Cannot open large project (keycloak)

Type: Bug

Thank you for the great work on the Java support for VS Code.

Sadly large projects seem to struggle with "Connection to server got closed. Server will not be restarted." issue.

Steps to reproduce:

1. Checkout https://github.com/keycloak/keycloak
2. Open this project in VS Code

The CPU utilization remains over 200% even after the "Server will not be restarted" message.

It would be great if it would be possible to open Keycloak in VSCode.

Tái hiện lỗi bằng cách mở repository Keycloak trong VS Code và kiểm tra các nhật ký máy chủ Java xung quanh kết nối đã đóng và mức sử dụng CPU cao. Bắt đầu với các mục trong annotation-processor stack ở AbstractJsonSchema và CustomResourceAnnotationProcessor, sau đó xác định liệu cyclic subGroups exception có gây ra server failure hay không. Hoàn tất khi Keycloak mở được và máy chủ Java vẫn chạy mà không xảy ra tình trạng CPU tăng vọt kéo dài.
