Spring ExceptionHandler does not work on a secured class/method

Affects: 5.0.7.RELEASE

---

On a RestController, it seems that exception handling does not work when the controller's class has bean proxied due to @PreAuthorize annotation.

In ExceptionHandlerExceptionResolver.java : the handled types to exception handlers mapping resolution uses proxied class instead of the original type (see line 455 : handlerMethod.getBeanType() )

The following (Kotlin) source code explain the problem (commenting the first line re-enable the exception handling... while disabling the security !)

    @PreAuthorize("hasAuthority('anyAuthority')")
    @RestController
    class AnyController : IAnyController {
        override fun doSomething(): ResponseEntity<AnyResponse> {
            throw ToBeHandledException()
        }

        @ExceptionHandler(ToBeHandledException::class)
        fun handleException(e: ToBeHandledException): ResponseEntity<Unit> =
            ResponseEntity.ok().build()
    }

I am not able to reproduce the issue. Can you provide a sample?

In ExceptionHandlerExceptionResolver.java : the handled types to exception handlers mapping resolution uses proxied class instead of the original type (see line 455 : handlerMethod.getBeanType() )

The bean type is initialized with ClassUtils.getUserClass(bean). It should be okay.
