org.springframework.boot.web.embedded.tomcat.ConnectorStartFailedException on IDEA Ultimate 2019.3

Gianmarco F. :

I have a project in which I'm working that it is made, among everything, with Java 11+Spring Boot+Gradle.
All of a sudden, when I press play on IntelliJ Idea Ultimate 2019.3 I'm getting the following error.

<String that tells the given command for launching the app>

 :: Spring Boot ::        (v2.1.4.RELEASE)

org.springframework.boot.web.embedded.tomcat.ConnectorStartFailedException: Connector configured to listen on port 8080 failed to start

    at it.niuma.epp.EPPApplication.main(EPPApplication.java:79)

Process finished with exit code 0

And that's just it. The code of the Main class is made just by these lines

@EnableScheduling
@EnableAsync
@SpringBootApplication(scanBasePackages = {list of packages})
public class EPPApplication implements WebMvcConfigurer {

    public static void main(String[] args) {
        /* Allows slash url encoding */
        // System.setProperty("org.apache.tomcat.util.buf.UDecoder.ALLOW_ENCODED_SLASH",
        // "true");
            SpringApplication.run(EPPApplication.class, args);

    }

And if I don't surround the SpringApplication.run in a try-catch scope, I wouldn't even get the error.
The project tries to boot on port 8080, which is not occupied by anything. In fact, by typing

netstat -ano|findstr "PID :8080"

on my Windows machine, this is the result shown

C:\Users\Gianmarco>netstat -ano|findstr "PID :8080"
  Proto  Indirizzo locale          Indirizzo esterno        Stato           PID
  TCP    0.0.0.0:8080           0.0.0.0:0              LISTENING       18152
  TCP    [::]:8080              [::]:0                 LISTENING       18152

When if I try to change to any other port possible, I always get the same error.

What am I missing? I've tried to see other similar questions on SO but nobody had my same issue

EDIT: The same happens on Eclipse as well

EDIT2: By following the debbuger starting from org.apache.catalina.connector.Connector.startInternal() I see that it even reaches the logger part in which it states that has started tomcat on port 8080 but this isn't logged on the console. Shortly after, I reach SpringApplication.java on line 400 which calls line 327 in which I see that a variable colled exceptionReporters (a collection) holds an expection. The following screenshot represent what this collection holds. After this point, though, it looks like I can't debug anymore but the application remains stuck

Andy Wilkinson :

Given the lack of logging output, you may have a problem with some logging related dependencies. For example, a dependency on commons-logging:commons-logging can cause problems and should be excluded in favour of org.springframework:spring-jcl. org.slf4j:jcl-over-slf4j should be treated similarly.

You can learn if you have either of these dependencies on the classpath using Gradle's dependencyInsight task:

gradle dependencyInsight --dependency commons-logging:commons-logging
gradle dependencyInsight --dependency org.slf4j:jcl-over-slf4j
