Spring boot 2.1.3.RLEASE to 2.6.6 upgrade and un-supported http method behaviour

Question

I was using spring 2.1.3.RELEASE before. Used to handle all un-supported HTTP methods and endpoints with an custom error like below and it worked;

/**
 * Handle all of the unsupported endpoints and methods with custom message
 */
@RequestMapping
public void notSupported(HttpServletRequest request) {
    throw new UnknownEndpointAndMethodException(request.getMethod(), request.getRequestURI());
}

Then I just used a global @ExceptionHandler for UnknownEndpointAndMethodException to return a custom error with HTTP status of my choice (mostly NOT_FOUND).

Now I have updated to 2.6.6 and the tests for wrong/missing URLs pass with expected custom error, meaning the i-handle-everything code works for missing URLs.

But, invalid HTTP method tests fails and triggers HttpRequestMethodNotSupportedException and since I havnt handled it, gives an INTERNAL_SERVER_ERROR.

So my question is, in which spring boot version this behavior has changed? Can I get the same all-in-one behavior in 2.6.6 like in 2.1.3.RELEASE?

NOTE: I went through the release docs(both old and new) and couldn't seem to find it.
