Java Maven Compilation Error "Unable to read class" with enum in it

Question

I'm stuck on this. My MacBookPro broke and I'm reinstalling the project in a Windows. I've installed Java & Maven. With mvn -version:

Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)
Maven home: C:\Software\apache-maven-3.6.3\bin\..
Java version: 13.0.2, vendor: Oracle Corporation, runtime: C:\Program Files\Java\jdk-13.0.2
Default locale: es_ES, platform encoding: UTF-8
OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows"

It worked on my MacBookPro and it works on colleagues linux & windows laptops. On finishing the compilation shows this error on most of the classes with enums on it:

2020-03-17 00:20:45,784 ERROR [CommonsLogger.java:42] : Unable to read class [es.ubiqua.compareme.actions.CmprmInitGetScreenCodeAction$EnumType]
java.lang.ArrayIndexOutOfBoundsException: Index 2560 out of bounds for length 188

The java error "java.lang.ArrayIndexOutOfBoundsException: Index 2560 out of bounds for length 188" is disconcerting on compilation. It shows the same figures for all the errors on other classes.

I tried to explicitly import, set as static, change the references to the enums with all the package-path, remove all array references inside enum, put the enums on specific files...

My code:

package es.ubiqua.compareme.actions;

import es.ubiqua.compareme.application.ScreenSetup.ListScreenSetup;
import es.ubiqua.compareme.domain.Entity.Customer.CustomerEntity;
import es.ubiqua.compareme.domain.Entity.ScreenSetup.ScreenSetupEntity;
import es.ubiqua.compareme.domain.Exception.RepositoryException;
import es.ubiqua.compareme.infrastructure.MariaDbEntity.Customer.CustomerMariaDb;
import es.ubiqua.compareme.infrastructure.MariaDbEntity.ScreenSetup.ScreenSetupMariaDb;
import org.apache.struts2.ServletActionContext;

import javax.servlet.http.HttpServletRequest;
import java.net.MalformedURLException;
import java.net.URL;
import java.util.Arrays;
import java.util.List;
import java.util.regex.Pattern;

public class CmprmInitGetScreenCodeAction extends CmprmAction
{
    //Request Parameters
    private int idCustomer;
    private String url;
    private int idScreen;

    //Response
    private ScreenSetupEntity screen;


    //Enums
    public enum EnumCondition
    {
        None(0),
        Equals(1),
        StartWith(2),
        Contains(3),
        MatchesRegEx(4);

        private int value;

        private EnumCondition(int value) {
            this.value = value;
        }

        private static EnumCondition[] allValues = values();

        public static EnumCondition fromOrdinal(int n) {return allValues[n];}

        public int getValue() {
            return value;
        }

        //Get the String Name of an EnumState
        public String toString()
        {
            return this.name();
        }

        public static String[] names() {
            return Arrays.toString(EnumCondition.values()).replaceAll("^.|.$", "").split(", ");
        }
    }


    public String execute()
    {
        HttpServletRequest request = ServletActionContext.getRequest();

        try
        {

Are any of your colleagues using Java 13? – Elliott Frisch Mar 16 '20 at 23:39 — Elliott Frisch, Mar 16 '20 at 23:39
Which Maven version and plugins versions do you use? – khmarbaise Mar 17 '20 at 00:12 — khmarbaise, Mar 17 '20 at 00:12

Thanks for the comments :) As @Elliott Frisch suggested, it was a problem with the Java version, installing the JDK 8 solved this compilation problem. But then I had a lot of other troubles with the libraries, the linux makefile, maven version...

What solved deffinetively my transition of project from MAC to Windows, was installing Ubuntu Bash for Windows 10 as descrived here: https://itsfoss.com/install-bash-on-windows/

I had to solve other issues, some of them described on this answer if it can help someone: https://stackoverflow.com/a/60737395/1655296

As a closure, I wonder why Java 13 doesn't like Enums, or at least the way I was using them. Some less busy day I will dig on this.
