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.

Riproduci il malfunzionamento aprendo il repository Keycloak in VS Code ed esamina i log del server Java relativi alla connessione chiusa e all’elevato utilizzo della CPU. Inizia dalle voci dello stack del processore di annotazioni in AbstractJsonSchema e CustomResourceAnnotationProcessor, quindi determina se l’eccezione relativa a subGroups ciclici causa il malfunzionamento del server. Il lavoro è completato quando Keycloak si apre e il server Java rimane in esecuzione senza un sovraccarico prolungato della CPU.
