Extension breaks "clipboardPasteAction" in Java files

[bevzzz]

When enabled, the VSCode extension prevents text from being pasted.

Environment

• Operating System: macOS Sonoma 14.3.1
• JDK version: 17
• Visual Studio Code version:

Version: 1.80.2 (Universal)
Commit: 2ccd690cbff1569e4a83d7c43d45101f817401dc
Date: 2023-07-27T21:05:41.366Z (9 mos ago)
Electron: 22.3.14
ElectronBuildId: 22695494
Chromium: 108.0.5359.215
Node.js: 16.17.1
V8: 10.8.168.25-electron.0
OS: Darwin x64 23.3.0

• Java extension version: 1.30.0

Steps to reproduce

1. Install "Language Support for Java(TM) by RedHat"
2. Open a .java file (other files, e.g. yaml are fine)
3. Copy and paste any amount of text (doesn't matter if with a shortcut or with mouse actions)

Once the extension is disabled, copy-paste works as usual.
Here's a relevant excerpt from Keyboard Shortcuts Troubleshooting log:
