Execute the following code with Concurrency preliminary test release 1
and see the result. retainAll() method of LinkedQueue doesn't return correct boolean value.
   

/* start of sample test code */
LinkedQueue < String > queue = new LinkedQueue < String> ();
       
queue.add("str1");
queue.add("str2");
queue.add("str3");
               
ArrayList list = new ArrayList();
list.add("str1");
list.add("str2");
System.out.println("status = " + queue.retainAll(list));
System.out.println(queue.toString());
/* end of sample test code */

This is only a backlog bug and added to bugtraq just for tracking purpose.
It has been fixed.
