### Adding New Features

1. Read related source files and tests
2. Write implementation following existing patterns
3. Add comprehensive tests
4. Run `mvn formatter:format license:format test`
5. Update JavaDoc for changed/new classes

     * This method searches for 'fess_ds++.xml' configuration files within JAR files
     * in the data store plugin directory and extracts component class names.
     *
     * <p>The method uses secure XML parsing features to prevent XXE attacks and
     * other XML-based vulnerabilities. Component class names are extracted from
     * the 'class' attribute of 'component' elements in the XML files.</p>
     *

 * to prevent hanging on problematic PDF files. It also extracts metadata from the PDF
 * document and includes it in the extraction result.
 *
 * <p>Features:
 * <ul>
 *   <li>Text extraction from PDF pages</li>
 *   <li>Embedded document extraction</li>
 *   <li>Annotation extraction (file attachments)</li>
 *   <li>Metadata extraction</li>

 *
 * <p>The robots.txt protocol is implemented according to the standard specification,
 * supporting pattern matching for user agents, path-based access control, and crawl delay settings.</p>
 *
 * <p>Key features:</p>
 * <ul>
 *   <li>Supports multiple user-agent directives with pattern matching</li>
 *   <li>Handles Allow and Disallow rules for path-based access control</li>
 *   <li>Manages crawl delay settings per user agent</li>

 * and reloads the properties if the file is updated. This class is thread-safe and
 * ensures that the properties are always up-to-date.
 *
 * <p>Key Features:
 * <ul>
 *   <li>Automatically reloads properties if the file is modified.</li>
 *   <li>Supports custom check intervals for file modification checks.</li>

/**
 * Secure credential storage with encryption at rest.
 *

 *
 * Features:
 * - Encrypts credentials at rest using AES-256-GCM
 * - Uses PBKDF2 for key derivation from master password
 * - Secure wiping of sensitive data
 * - Thread-safe operations
 * - Protection against timing attacks
