ResolvableType - java.lang.IllegalArgumentException: Mismatched number of generics specified #1401

a-locatelli · 2021-12-23T14:30:57Z

I'm trying to build an application using cloud gcp data datastore.
This app expose a rest api endpoint for receiving data and make a call to gcp datastore for saving data.

RestController:

@RestController
public class DevicesApiController implements DevicesApi {
	
	@Autowired
	private DeviceManager deviceManager;
	
	@Autowired
	private DeviceRepository deviceRepository;
	
	@Override
	public ResponseEntity<Void> postDevice(@Valid DevicePost devicePost) {
		Device device = deviceManager.createDevice(devicePost);
		deviceRepository.save(device);
		
		HttpHeaders responseHeaders = new HttpHeaders();
		responseHeaders.set(HttpHeaders.LOCATION, null);
		
		return ResponseEntity.status(HttpStatus.CREATED).headers(responseHeaders).build();
	}

}

The DeviceRepository is an interface which extend the DatastoreRepository:

public interface DeviceRepository extends DatastoreRepository<Device, Long> {
	
}

While running the application normally doesn't make problem, when i build the native image i get this error from spring-aot-maven-plugin:

The method snippet (from org.springframework.core.ResolvableType )

public static ResolvableType forClassWithGenerics(Class<?> clazz, ResolvableType... generics) {
	Assert.notNull(clazz, "Class must not be null");
	Assert.notNull(generics, "Generics array must not be null");
	TypeVariable<?>[] variables = clazz.getTypeParameters();
	Assert.isTrue(variables.length == generics.length, "Mismatched number of generics specified");
	Type[] arguments = new Type[generics.length];
	for (int i = 0; i < generics.length; i++) {
		ResolvableType generic = generics[i];
		Type argument = (generic != null ? generic.getType() : null);
		arguments[i] = (argument != null && !(argument instanceof TypeVariable) ? argument : variables[i]);
	}
	ParameterizedType syntheticType = new SyntheticParameterizedType(clazz, arguments);
	return forType(syntheticType, new TypeVariablesVariableResolver(variables, generics));
}

From debugging the error: java.lang.IllegalArgumentException: Mismatched number of generics specified is raised when processing class org.springframework.cloud.gcp.data.datastore.repository.support.DatastoreRepositoryFactoryBean.

Method variables involved:
clazz = org.springframework.cloud.gcp.data.datastore.repository.support.DatastoreRepositoryFactoryBean

variables = 
- [0]	TypeVariableImpl<D>  (id=372) -> DatastoreRepository entity class
- [1]	TypeVariableImpl<D>  (id=373)-> DatastoreRepository entity id

generics = 
- [0]	ResolvableType  (id=395) -> DeviceRepository (which extends DatastoreRespository)
- [1]	ResolvableType  (id=396) -> DatastoreRepository entity class
- [2]	ResolvableType  (id=397) -> DatastoreRepository entity id

The problem seems to be the generics[0] because it is the interface itself.

Thanks for the report. Can you share a small sample that we can run ourselves?

ch4mpy · 2021-12-27T16:58:57Z

PR #1408 reproduces similar issue with a minimal change set from data-jpa sample

snicoll · 2022-01-12T13:28:29Z

I think the problem is that the FactoryBean that handles the repository type might not be the one we thought it would be. DatastoreRepositoryFactoryBean has two generics, not three.

snicoll · 2022-01-12T13:38:52Z

I've reproduced the problem in a unit test.

snicoll · 2022-01-13T12:41:57Z

This turned out to be quite tricky to fix. I have a first draft that I'd like to review once more.

ch4mpy · 2022-01-14T04:07:09Z

@snicoll I have a new exception (but stil related to generics) with latest snapshot on api/order-api module from this repo:

@ch4mpy thanks for testing the snapshot!

Any updates on @ch4mpy's latest error?
I have the same one even after removing Mockito (as was recommended in a different issue)

As far as I am aware, I did fix that (see the reopen). If you're experiencing an issue still please open a new issue with a small sample that we can run ourselves.
