TypeError: Cannot read property 'rows' of undefined

Whenever I open my project, the extension fails with:

ERR Cannot read property 'rows' of undefined: TypeError: Cannot read property 'rows' of undefined
    at u.open (/home/x/.vscode/extensions/redhat.java-0.76.0/dist/extension.js:15:69804)

    at processTicksAndRejections (internal/process/task_queues.js:97:5)

I inspected the extensions file and it seems that e is undefined:

open(e){
   s.serverTasks.suggestTaskEntrySize(e.rows-1);
   const t=s.serverTasks.getHistory();
   this.printTasks(t)
}

and then after a few seconds:

ERR The request (id: 1, method: 'textDocument/documentSymbol') has been cancelled: Error: The request (id: 1, method: 'textDocument/documentSymbol') has been cancelled

Here are some info messages it shows before:

This previously worked so I'm not sure what changed.

Environment

• Operating System: Debian GNU/Linux 10 (buster)
• JDK version: OpenJDK Java 11 AMD64, project JDK: 1.8
• Visual Studio Code version: 1.54.3
• Java extension version: 0.76.0

Bắt đầu với stack trace được báo cáo trong extension.js được đóng gói của redhat.java 0.76.0 và tái hiện lỗi khi mở project bằng các phiên bản VS Code và Java được liệt kê. Theo dõi đường dẫn khởi động task quanh open(e) và xác định tại sao đối số của nó là undefined; hoàn tất khi việc mở project không còn gây ra rows TypeError và yêu cầu document-symbol tiếp theo không bị hủy.
