> As specificaton says, if collection fits into array with room to spare, the
> element in the array immediately following the end of the collection must be
> set to null.
> Test to reproduce:
> import junit.framework.TestCase;
> import java.util.concurrent.*;
> public class Test extends TestCase {
>         public void testcase() {
>                 LinkedBlockingQueue lbq = new LinkedBlockingQueue();
