I am migrating Java 8 application to JDK11 (early access). New code suppose to be a module. It read an error message from property file in Java8, but return 'null' in Java 11. Any help how to load/read resourceInputStream from /src/resources/messges/myerrors.properties
Any help appreciated.

Java :
package com.acme;
import java.util.Locale;
import java.util.PropertyResourceBundle;
import java.util.ResourceBundle;
public class Main {
public static void main(String args[]){
Main m=new Main();
m.process();
}
void process(){
PropertyResourceBundle prb= (PropertyResourceBundle)ResourceBundle.getBundle("messages.mymessages",Locale.getDefault());
String key="key1";
String value= prb.getString(key);
System.out.println(key+":"+value);
}
}
Exception in thread "main" java.util.MissingResourceException: Can't find bundle for base name messages.mymessages, locale en_US

For the code above solution is: "--class-path ./out/production/resources". I figured out. Also, another variation is this. I have a set of JUnits. During test code need to generate error message from /src/main/resources/messages/mymessages.properties. However, the test wasn't able to "see" resources from "main". After 1 day of trying different combinations solution was: "--module-path ...pathTotestClassesOrOtherProductionClasses;$buildDir/resources/main;$buildDir/resources/test;". So you need to add ".../resources/main" as module path
