## Language Detection and Selection

### User Interface Language

Fess determines the UI language in this order:

/**
 * Centralized resource management for preventing resource leaks.
 * Tracks all AutoCloseable resources and ensures proper cleanup.
 *
 * Features:
 * - Automatic resource cleanup with weak references
 * - Resource leak detection
 * - Resource usage monitoring
 * - Periodic cleanup of abandoned resources
 * - Detailed resource tracking and reporting
