Files in this directory are data for Go's API checker ("go tool api", in src/cmd/api).

Each file is a list of API features, one per line.

go1.txt (and similarly named files) are frozen once a version has been
shipped. Each file adds new lines but does not remove any.

except.txt lists features that may disappear without breaking true
compatibility.

Starting with go1.19.txt, each API feature line must end in "#nnnnn"

### Argument Validation

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`

                    result.getMissingArtifacts(),
