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.

Reproduce el fallo abriendo el repositorio de Keycloak en VS Code e inspecciona los registros del servidor Java alrededor de la conexión cerrada y del uso elevado de CPU. Comienza con las entradas de la pila del procesador de anotaciones en AbstractJsonSchema y CustomResourceAnnotationProcessor; después, determina si la excepción de subGroups cíclicos provoca el fallo del servidor. Se considera terminado cuando Keycloak se abre y el servidor Java permanece en ejecución sin un uso de CPU descontrolado y sostenido.
