Use `AssertionUtil` at method entry:
- `AssertionUtil.assertArgumentNotNull("argName", value)`
- `AssertionUtil.assertArgumentNotEmpty("argName", value)`

### Exception Handling

- Wrap checked exceptions in runtime exceptions from `org.codelibs.core.exception`
- Use error codes (e.g., "ECL0008" = null argument)

### Test Structure

- JUnit 4 + Hamcrest matchers
- Test class: `{ClassName}Test.java`
