### 5. Rebuild the Project

```bash
mvn clean package
```

### 6. Test the New Language

1. **Start Fess:**
   ```bash

     *
     * One thing to *avoid* is a change to make each Logger user use memoizingSupplier directly:
     * That may introduce an extra class for each lambda (currently a dozen).
