    ConcurrentModificationException on Archive.delete()

    Mathias Deshayes Newbie

      Hi,

       

      I'm trying to use Shrinkwrap to delete a folder in a JavaArchive (jar). My jar is quite simple, it contains only one folder named resources and this folder contains two files :

       

      myJavaArchive.jar:

      /resources/

      /resources/bar.txt

      /resources/foo.txt

       

      So I create a JavaArchive from my JAR file and I call delete method on "/resources" folder (see below) but it causes a ConcurrentModifictionException.

       

      My code :

       

      package com.test;
        
      import java.io.File;
        
      import org.jboss.shrinkwrap.api.ShrinkWrap;
      import org.jboss.shrinkwrap.api.spec.JavaArchive;
        
      public class Main {
          public static void main(String[] args) {
              JavaArchive archive = ShrinkWrap.createFromZipFile(JavaArchive.class,
                      new File(Main.class.getResource("/myJavaArchive.jar").getFile()));
              System.out.println(archive.toString(true));
              archive.delete("/resources");
          }
      }
      
      

       

      The stack trace :

       

      Exception in thread "main" java.util.ConcurrentModificationException
