## Code Conventions

### Java Style

- **Formatter**: Eclipse formatter at `src/config/eclipse/formatter/java.xml`
- **Indentation**: 4 spaces (no tabs)
- **Line Length**: 140 characters max
- **License Headers**: Required (use `mvn license:format`)

### Naming Conventions

| Type | Convention | Example |
|------|-----------|---------|

4. **Edge Cases**: Null, empty, and boundary conditions are covered
5. **Resources**: Test resources are properly managed and cleaned up

## Contributing

When adding new tests:
1. Follow the existing naming convention: `test_<method>_<scenario>_<expectedResult>`
2. Add clear JavaDoc comments explaining the test purpose
3. Ensure tests are independent and can run in any order
4. Clean up resources in finally blocks or use try-with-resources

├── fess_message.properties         # Base English messages (fallback)
└── fess_message_[locale].properties # Language-specific messages (~200 lines)
```

### Naming Convention

- **Language only**: `fess_label_en.properties`, `fess_label_ja.properties`
- **Language + Region**: `fess_label_pt_BR.properties`, `fess_label_zh_CN.properties`, `fess_label_zh_TW.properties`

## ✨ Features

### Core Utilities
- **Bean Manipulation** (`org.codelibs.core.beans`) - JavaBeans metadata handling, property access, and object conversion with comprehensive `BeanDesc` system
- **Type Conversion** (`org.codelibs.core.convert`) - Comprehensive utilities for converting between Java types with null-safe operations and support for all primitive types

        assertEquals(threadCount * operationsPerThread, successCount.get());
        assertTrue(overallTimeMs < 1000, "Operations should complete quickly without lock contention");

        pool.close();
    }

    /**
     * Test buffer cache performance with concurrent operations
     */
    @Test
    public void testBufferCachePerformance() throws Exception {

```

### Connection Pool Tuning

```java
container.singleton("httpClient", HcHttpClient.class, client -> {
    client.setMaxConnections(200);          // Total connections
    client.setMaxConnectionsPerRoute(20);   // Per-host connections
    client.setConnectionTimeout(30000);     // Connection timeout
    client.setSocketTimeout(60000);         // Read timeout
});

        @Test
        public void testGetTypeForFile() throws Exception {
            // Mocking underlying connection and info retrieval is complex.
            // This test focuses on the logic based on the URL structure.
            SmbFile file = new SmbFile("smb1://server/share/file.txt");
            // Without a real connection, getType relies on path parsing.
            // getUncPath0() will result in a path > 1, so it should be TYPE_FILESYSTEM

    }

        super(connection.getURL());

        requestProperties = new HashMap();
    }

    @Override

        URLConnection connection = handler.openConnection(url);

        assertNotNull(connection, "Connection should not be null.");
