### 4. Regenerate Auto-Generated Java Classes

Fess uses DBFlute's LastaFlute FreeGen to automatically generate Java constants from property files.

Run the regeneration command:

```bash
# Option 1: Using Maven from project root
mvn dbflute:freegen

# Option 2: Using DBFlute manage script
cd dbflute_fess
./manage.sh    # On Linux/Mac
manage.bat     # On Windows

            // Initialize the data buffer with proper SMB2 header structure
            SMBUtil.writeInt4(0xFE534D42, data, 0); // SMB2 signature
            SMBUtil.writeInt4(0x0000, data, 12); // Command = 0
            SMBUtil.writeInt4(0x0000, data, 16); // Flags = 0

            CommonServerMessageBlock request = mock(CommonServerMessageBlock.class);

        byte[] header = Arrays.copyOf(SMBUtil.SMB2_HEADER, SMBUtil.SMB2_HEADER.length);
        // Mark as server->client response for realism
        SMBUtil.writeInt4(0x00000001, header, 16); // Flags
        // Command SMB2_CREATE (0x0005)
        SMBUtil.writeInt2(0x0005, header, 12);
        // Some message id
        SMBUtil.writeInt8(1L, header, 24);
        return header;
    }
