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

Bắt đầu bằng cách tái hiện việc hoàn thành trong một tệp .java và lần theo lỗi được ghi lại tại ProjectUtils.java:80 qua parseProjects và getTestSourcePaths. Kiểm tra TestDelegateCommandHandler.executeCommand và đường dẫn gọi của org.eclipse.jdt.ls.core. Được xem là hoàn tất khi nhập "class" tạo ra các đề xuất đoạn mã Java mong đợi mà không có NullPointerException đã báo cáo.
