# ADR-0008 - Use NullAway for null checking

## Date

2025-08-06

## Context

Our codebase uses `null` extensively to represent an absence of value or optionality of the argument.
We utilize nullness annotations in Java code and somewhat rely on IDE warnings to guide us.
However, the Java code we have is not fully annotated, which causes several consequences:
* IDE warnings can be misleading

            classExtensionDoc.getExtensionClasses().put(extension.getExtensionId(), model.getClassDoc(extension.getExtensionClass()));
        }
        for (ClassExtensionDoc extensionDoc : plugins.values()) {
            build(extensionDoc);
            classDoc.addClassExtension(extensionDoc);
        }

Se você se comunicar com essa *operação de rota* enviando dois cabeçalhos HTTP como:

```
X-Token: foo
X-Token: bar
```

A resposta seria como:

```JSON
{
    "X-Token values": [
        "bar",
        "foo"
    ]
}
```

## Recapitulando { #recap }

Declare cabeçalhos com `Header`, usando o mesmo padrão comum que utiliza-se em `Query`, `Path` e `Cookie`.

                if (vertex != null) {
                    addEdge(projectVertex, vertex, project, projectMap, force, safe);
                }
            } else {
                for (Vertex vertex : vertices.values()) {
                    addEdge(projectVertex, vertex, project, projectMap, force, safe);
                }
            }
        }
    }

    private void addEdge(
            Vertex fromVertex,

            "loc": [
                "path",
                "item_id"
            ],
            "msg": "value is not a valid integer",
            "type": "type_error.integer"
        }
    ]
}
```

以下のようなテキスト版を取得します:

```
1 validation error
path -> item_id
  value is not a valid integer (type=type_error.integer)
```
