Spring boot application gives "unable to start tomcat" exception with spring-boot-starter-actuator - spring-boot

Question

I had my spring-boot application, with spring-boot-starter-web, then I added spring-boot-starter-actuator to gradle file. There is no compilation error. But when i try to run the server it gives the following exception.
my build.gradle content (only the main ones included )
plugins {
id 'org.springframework.boot' version '2.1.3.RELEASE'
} ...........
compile "org.springframework.boot:spring-boot-starter-actuator"
compile group: 'io.micrometer', name: 'micrometer-registry-prometheus', version: '1.1.3' .........
my application.properties content
server.port = 2128
spring.couchbase.env.timeouts.connect=10000
spring.couchbase.env.timeouts.query=180000
spring.couchbase.env.timeouts.view=20000
spring.couchbase.bootstrap-hosts=localhost
spring.couchbase.bucket.name=localdb
spring.couchbase.bucket.password=*****
spring.data.couchbase.repositories.type=auto
spring.data.couchbase.auto-index=true
server.compression.enabled=true
server.compression.mime-types=application/json,text/plain
spring.servlet.multipart.enabled=true
spring.servlet.multipart.maxFileSize=50MB
spring.servlet.multipart.maxRequestSize=50MB
my Application.java
#SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
Gives the following exception while starting the server.
org.springframework.context.ApplicationContextException: Unable to start web server;
nested exception is org.springframework.boot.web.server.WebServerException: Unable to start embedded Tomcat
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'servletEndpointRegistrar' defined in class path resource

nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'healthIndicatorRegistry' defined in class path resource [org/springframework/boot/actuate/autoconfigure/health/HealthIndicatorAutoConfiguration.class]: Bean instantiation via factory method failed
Any helpful hints?

I was finally able to start the application after I turned off default health checks via the following entry in application.properties file
management.health.defaults.enabled=false
