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

redhat.java 0.76.0 のバンドルされた extension.js に報告されているスタックトレースから始め、記載された VS Code と Java のバージョンでプロジェクトを開いたときに失敗を再現してください。open(e) 周辺のタスク起動パスを追跡し、その引数が undefined である理由を特定してください。プロジェクトを開いても rows TypeError が発生せず、その後の document-symbol リクエストがキャンセルされなければ完了です。
