- **Assertion-based validation** - All methods validate inputs using `AssertionUtil.assertArgumentNotNull()` and `AssertionUtil.assertArgumentNotEmpty()`
- **Exception wrapping** - Checked exceptions are consistently wrapped in runtime exceptions (e.g., `ClassNotFoundException` → `ClassNotFoundRuntimeException`)
