L'important à garder à l'esprit est que la clé `sub` doit contenir un identifiant unique dans toute l'application, et ce doit être une chaîne de caractères.

     * Creates a larger buffer suitable for testing negotiate contexts.

    private byte[] createLargeBufferForContexts() {

### Cache Behavior

- Language items are cached for 1 hour by `SystemHelper`
- Restart the application after adding new languages

### Auto-Generated Files

Never edit these files manually (marked with `@author FreeGen`):
- `FessLabels.java`
- `FessMessages.java`

Always regenerate them using `mvn dbflute:freegen`
