# SMB3 Advanced Features Implementation Plan

## Overview
This document outlines the implementation plan for advanced SMB3 features that are currently not implemented in JCIFS. These features are essential for enterprise-grade SMB3 support, providing enhanced performance, reliability, and scalability.

## Implementation Phases

### Phase 1: SMB3 Lease Implementation (Foundation)
**Priority: HIGH** | **Estimated Effort: 3-4 weeks**

 * Tests for the NdrObject abstract class.
 * This test uses a concrete implementation to verify the abstract contract.

        assertEquals(2, notifications.size());

        // Try to modify returned list - behavior depends on implementation
        // This tests that the implementation properly handles list modifications
        try {
            notifications.clear();
            // If this succeeds, the implementation allows modification
            assertTrue(notifications.isEmpty());

     * @return the processed result data
