@Test
public void test() {

FormBody formBody = new FormBody.Builder()
.add("sourceType", "Test")
.build();
JSON.toJSONString(formBody);

}
}
```

### 期待的正确结果

Start by reproducing the provided JUnit case with JSON.toJSONString and inspect ObjectWriterBaseModule.java, ObjectWriterProvider.java, and ObjectWriterCreator.java at the stack-trace locations. Trace why the FormBody field whose key contains Type produces a null paramNames value; done means the example serializes normally without the JSONException or NullPointerException.
