To Reproduce
Steps to reproduce the behavior:

1. Start Eclipse
2. Check logs
3. See error

Expected behavior
No errors expected during Eclipse boot.

Reproduce the issue by starting Eclipse on Windows 10 and inspect the startup logs. The reported entry point is dist/tfidfWorker.js, involving PersistentTfIdf and TfidfWorker with SQLite error code 5; done means Eclipse starts without the database-locked error.
