Better ForkJoinPool behavior in OpenJDK 8

Issue

• Running java class for example: Test2.java throws an exception

  import java.io.FilePermission;
  import java.security.AccessController;
  import java.util.concurrent.ForkJoinPool;
  import java.util.concurrent.ForkJoinWorkerThread;
  import java.util.concurrent.RecursiveTask;
  
  public class Test2 {
  
      static void testPermission() {
          AccessController.checkPermission(new FilePermission(System.getProperty("java.class.path")+"/a", "read"));
      }
  
      public static void main(String[] args){
          testPermission();
  
          ForkJoinPool pool = new ForkJoinPool(1);
  
          pool.invoke(new RecursiveTask<Object>() {
              @Override
              protected Object compute() {
                  testPermission();
                  System.out.println("done");
                  return null;
              }
          });
  
          pool.shutdown();
      }
  }
  

• The exception is:
