Commencez par WorkspaceDiagnosticsHandler.java, en particulier convertRange et toDiagnostic, qui sont mentionnés dans la stack trace. Reproduisez le scénario d’erreur sémantique dans un fichier Java dans l’environnement VS Code et extension Java indiqué, puis déterminez pourquoi BadLocationException empêche l’apparition des diagnostics. Le travail est terminé lorsque les erreurs sémantiques s’affichent sans l’exception.
