Cglib proxies created by MvcUriComponentsBuilder should be processed at build-time

Affects: 6.0.0

I have a simple controller that goes like

    @PostMapping
    public ResponseEntity<?> insert(
            @RequestBody @Valid CustomerApiDTO customerDTO) {

        var customerEntity = customerMapper.map(customerDTO);

        customerRepository.saveAndFlush(customerEntity);

        var uri = MvcUriComponentsBuilder.fromMethodCall(
                MvcUriComponentsBuilder.on(CustomerApiController.class)
                        .findByCustomerNumber(customerDTO.getCustomerNumber())  
        ).build();
        return ResponseEntity.created(uri.toUri()).build(); 
    }

With AOT generating the proxy for the controller this fails with:

java.lang.ArrayIndexOutOfBoundsException: Index 1 out of bounds for length 1
        at de.eiswind.training.spring.rest.customer.responseentity.CustomerApiController$$SpringCGLIB$$1.setCallbacks(<generated>)
        at org.springframework.web.servlet.mvc.method.annotation.MvcUriComponentsBuilder$ControllerMethodInvocationInterceptor.initProxy(MvcUriComponentsBuilder.java:814)
        at org.springframework.web.servlet.mvc.method.annotation.MvcUriComponentsBuilder.controller(MvcUriComponentsBuilder.java:383)

Please let me know if I can provide any further help with this.

Please forgive: I am not sure where to file this issue as it goes with AOT.

Start with MvcUriComponentsBuilder.controller and ControllerMethodInvocationInterceptor.initProxy in MvcUriComponentsBuilder.java, then trace how AOT-generated controller proxies are created. Reproduce the reported ArrayIndexOutOfBoundsException with fromMethodCall and verify that controller proxies work without the runtime callback mismatch. Add or update a regression test covering this AOT proxy path.
