内存泄漏问题咨询

我在使用插件类加载器的时候，插件停止的时候会，清理缓存，
```java
ObjectWriterProvider writerProvider = JSONFactory.getDefaultObjectWriterProvider();
ObjectReaderProvider readerProvider = JSONFactory.getDefaultObjectReaderProvider();
writerProvider.clear();
readerProvider.clear();

Map pluginClassLoaders1 = getPluginClassLoaders();
pluginClassLoaders1.forEach((k, v) -> {
log.info("stopPlugins::plugin:{}, classloader:{}", k, v);
writerProvider.cleanup(v);
readerProvider.cleanup(v);
});
```

如果多次重新加载，在fastjson2会出现Caused by: java.lang.OutOfMemoryError: Metaspace，我该怎么协助排查下呢
```bash

```

Start by tracing ObjectReaderCreatorASM.java:602 and ObjectReaderProvider.java:763-845 from the reported JSON.parseObject call in DeviceClient.java:187. Reproduce repeated plugin reloads while examining the writerProvider and readerProvider cleanup calls shown in the issue. Done means the source of the Metaspace growth is identified and a repeatable diagnostic or verified fix is documented.
