Using TinyRadius in Spring Boot Service failing to start tomcat - spring-boot

Question

I am trying to create a spring boot service using TinyRadius library. Consumers will call this service passing UserName & Password and I need to connect to the radius server for authentication. I am using IntelliJ for development. I have included below TinyRadius gradle dependency in gradle file
compile(group: 'org.tinyradius', name: 'tinyradius', version: '1.1.0')
but when I start my application inside IntelliJ it throws below error. Removing the above dependency and commenting out Radius Server code Tomcat inside IntelliJ starts but as soon as I have tinyradius dependency it fails to start.
[ main] o.s.b.w.embedded.tomcat.TomcatWebServer : Tomcat

Here is a sample code that I have in the controller so far. I am just trying to see if the server starts up and then can proceed. Any help is appreciated on how to implement this inside spring boot webservice
import org.tinyradius.packet.AccessRequest;
import org.tinyradius.packet.RadiusPacket;
import org.tinyradius.util.RadiusClient;
public void connect() throws Exception{
RadiusClient rc = new RadiusClient("radiusserver", "secretcode");
rc.setAuthPort(9999);
rc.setRetryCount(4);
rc.setSocketTimeout(30000);
AccessRequest ar = new AccessRequest("name", "pwd");
RadiusPacket response = rc.authenticate(ar);
}
