java - Wildfly response 404 when url ends in .xhtml

Question

I have the following endpoint in Spring Boot:

 @RestController
    @RequestMapping(value = "/")
    class HelloXhtml {

    @RequestMapping(value = {"/{app}/form.xhtml"}, method = {RequestMethod.GET},
            produces = {APPLICATION_XHTML_XML_VALUE})
    public ResponseEntity<String> getFormDefinitionXml(
            @PathVariable(name = "app") String app) {
            return new ResponseEntity<>("<fruit>apple</fruit>", HttpStatus.OK);

    }
}

if I run it with embedded Tomcat everything works fine but on Wildfly 20.0.0-Final this specific endpoint throws 404.

The endpoint fails with 404 when the @RequestMapping value ends in ".xhtml" like this:

@RequestMapping(value = {"/{app}/form.xhtml"}

I tried a workaround by changing @RequestMapping string to:

@RequestMapping(value = {"/{app}/{whatever}"}

It produced the same result: it worked as expected when the "whatever" parameter was any string and returned 404 error when I passed in a filename ending in xhtml (eg.: apple.xhtml) as parameter.

What makes Wildfly discard any url ending in xhtml and return 404, and how can I turn off this behaviour?

EDIT:

I went in for another round. I created a sample spring application to produce the behaviour:

Java code:

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

import lombok.extern.slf4j.Slf4j;
import org.springframework.format.annotation.DateTimeFormat;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.*;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

import java.time.ZonedDateTime;

import static org.springframework.http.MediaType.APPLICATION_XHTML_XML_VALUE;
import static org.springframework.http.MediaType.APPLICATION_XML_VALUE;

@SpringBootApplication
public class DemoApplication  extends SpringBootServletInitializer {

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

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(DemoApplication.class);
    }

}

@RestController
@RequestMapping(value = "/persistence/crud")
class HelloXhtml {


    @RequestMapping(value = {"/{app}/{form}/form/{formXml}"}, method = {RequestMethod.GET}, produces = {APPLICATION_XHTML_XML_VALUE})
    public ResponseEntity<String> getFormDefinitionXml(
            @PathVariable(name = "app") String app) {
            return new ResponseEntity<>("<fruit>pear</fruit>", HttpStatus.OK);

    }
}
