Review Comment:
   The ArrayList should use generic type parameter `ArrayList<String>` instead 
of raw type to avoid unchecked warnings and provide type safety.

Review Comment:
   The documentation states '--password pa' but should be updated to clarify 
this is a simplified test password. Consider documenting why this specific 
value was chosen or if it's a placeholder that should be changed in production 
environments.
   ```suggestion
        * to the end of the original argument list before delegating to 
HugeGraphLoader.
        * <p>
        * <b>Note:</b> The password "pa" is a simplified test password used 
only for testing purposes.
        * It is a placeholder and <b>must be changed</b> in production 
environments to a secure value.
        * The choice of "pa" is arbitrary and intended to facilitate automated 
testing.
   ```

Review Comment:
   After removing `System.exit(1)`, the method now returns normally after an 
error. This could cause confusion as the error is printed but execution 
continues in the calling context. Consider documenting this behavior change or 
ensuring callers check for errors appropriately.
   ```suggestion
               System.exit(1);
   ```
