Code completion does not insert parentheses and parameter suggestions

Code completion fails to insert parantheses and parameter suggestions when invoked on a type for the first time.

Environment

• Operating System: Ubuntu 22.04.4 LTS
• JDK version: java-21-openjdk-amd64
• Visual Studio Code version: 1.91.0
• Java extension version: 1.32.0

Steps To Reproduce

1. Open minimal Java Maven Project (Sample GitHub Repo)
2. Open Java file App.java
3. (Make sure that Language Server workspace is cleaned)
4. In line 19, enter set. and wait for completion list to appear
5. Enter clo to filter completion list entries
6. Hit <Enter> to select entry clone() from completion list

Current Result

set.clo gets expanded to set.clone

Expected Result

set.clo gets expanded to set.clone()

Additional Informations

• When completion item is focussed, completion item details (JavaDoc) cannot be displayed.
• Language client logs report an error every time the cursor keys are used to navigate the completion list (client.log)
• When completion item is selected (hitting <Enter>), language server reports an error (server.log)
• When triggering the completion list a second time, completion works as expected
• Reproduction can be repeated after cleaning Java Language Server workspace
• When reproducing the issue, I only had these extensions enabled:
  

Reproduisez le problème dans le projet Java Maven minimal en ouvrant App.java, en nettoyant l’espace de travail de Language Server et en sélectionnant clone() après avoir filtré la liste de complétion. Lisez client.log et server.log en parallèle du premier appel de complétion. C’est terminé lorsque le premier appel insère clone(), affiche les détails de la complétion et ne signale plus les erreurs de navigation ou de sélection décrites.
