Current Result

Within a .java file, typing "class", amongst others, does not offer any code snippets.

Expected Result

Within a .java file, typing "class" should result in code snippet suggestions, as per https://code.visualstudio.com/docs/java/java-tutorial

Additional Informations

Inizia riproducendo il completamento in un file .java e seguendo l’errore registrato in ProjectUtils.java:80 attraverso parseProjects e getTestSourcePaths. Ispeziona TestDelegateCommandHandler.executeCommand e il percorso delle chiamate di org.eclipse.jdt.ls.core. Il lavoro è completato quando digitando "class" vengono prodotti i suggerimenti di snippet Java attesi senza la NullPointerException segnalata.
