o.apache.coyote.http11.Http11Processor Error processing request | while opening localhost:8080

I am trying to create Jsp's in localhost:8080 using Spring-Boot, Spring-mvc and tomcat-jasper. However when i open localhost:8080/, every time i get an exception which seems related with tomcat-jasper:

ERROR 5488 --- [nio-8080-exec-1] o.apache.coyote.http11.Http11Processor : Error processing request java.lang.NoSuchMethodError: 'void org.apache.tomcat.util.buf.UDecoder.convert(org.apache.tomcat.util.buf.ByteChunk, org.apache.tomcat.util.buf.EncodedSolidusHandling)' and continues...

I am using 3 files currently and added them here.

HomeController.java

package com.avalon.springmvcboot;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HomeController {

    @RequestMapping("/")
    public String home() {
       return "index.jsp";
    }
}

SpringmvcbootApplication.java

package com.avalon.springmvcboot;

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

@SpringBootApplication
public class SpringmvcbootApplication {

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

}

index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>

<!DOCTYPE html>
  <html>
    <head> 
      <meta charset="UTF-8"> 
      <title>Insert title here</title>
    </head>
  <body>
    Hello World!
  </body>
</html>

build.gradle

plugins {
    id 'org.springframework.boot' version '2.4.3'
    id 'io.spring.dependency-management' version '1.0.11.RELEASE'
    id 'java'
}

group = 'com.avalon'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '14'

repositories {
    mavenCentral()
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation 'org.apache.tomcat:tomcat-jasper:9.0.21'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
}

test {
    useJUnitPlatform()
}

System Information: OpenJDK Java 15, Windows 10 IDE: Visual Studio Code

Any helps will be appreciated! Best regards...

It seems wrong tomcat version used at runtime.

void org.apache.tomcat.util.buf.UDecoder.convert(org.apache.tomcat.util.buf.ByteChunk, org.apache.tomcat.util.buf.EncodedSolidusHandling) is only available at tomcat 9

tomcat below 9

tomcat 9
