HttpMessageConverterExtractor (v. 5.3.22) not respecting response class / responds type of VaultResponses

spring cloud version: 2021.0.3
spring version: 2.7.3 (Spring boot starter)

the vault library doesn't seem to be respecting the response type as it passes it in to HttpMessageConverterExtractor
internally.

** note** please look at the screenshots of my debugger - you will see that HttpMessageConverterExtractor cannot properly parse VaultResponses

Ex:

public class SomeClass {
}

@SpringBootApplication
public class VaultdebugApplication {
	@Bean void createBean() {
		List<HttpMessageConverter<?>> messageConverters = new ArrayList<>();
		messageConverters.add(new ByteArrayHttpMessageConverter());
		messageConverters.add(new StringHttpMessageConverter());
		messageConverters.add(new ResourceHttpMessageConverter(false));
		HttpMessageConverterExtractor x = new HttpMessageConverterExtractor(SomeClass.class, messageConverters);
	}
	public static void main(String[] args) {
		SpringApplication.run(VaultdebugApplication.class, args);
	}
}

the above works - HttpMessageConverterExtractor recognizes SomeClass.class as the response type one I trace it through the debugger.

however - when I try to read a secret from a vault Versioned backend (kv2) for whatever reason running the debugger at that same place shows that HttpMessageConverterExtractor will not recognize SomeClass.class.

@SpringBootApplication
public class VaultdebugApplication {
	@Bean
	public Secrets secrets(VaultTemplate operations) {
		VaultResponseSupport<SomeClass> response = operations.read("some/vault/path", SomeClass.class);
		System.out.println(response.getRequiredData()); // results in null
		System.out.println(response.getData()); // results in null

		return null;
	}
	public static void main(String[] args) {
		SpringApplication.run(VaultdebugApplication.class, args);
	}
}

in fact you can even see that - whatever is passed into Type responseType field isn't a class but an instance of VaultResponses.

Bắt đầu với VaultTemplate.read(..., SomeClass.class), VaultResponseSupport và lệnh gọi HttpMessageConverterExtractor được示示 trong báo cáo; tái hiện sự cố với backend Vault KV2 và kiểm tra responseType được truyền vào extractor. Truy vết các bài kiểm thử chuyển đổi response hiện có và bổ sung coverage cho thấy class được yêu cầu được giữ nguyên và dữ liệu của nó được điền vào.
