blockFinalizerThread looks buggy to me.
103 private static void blockFinalizerThread() throws
InterruptedException {
104 System.out.println("trying to block the finalizer thread");
105 o1 = new MyObject();
106 o1 = null;
107 System.gc();
108 System.runFinalization();
109 finRunLatch.await();
110 }
Why are you calling System.runFinalization() ? You are trying to block the
primary finalizer thread; you definitely don't want the object to be
handled by the secondary finalizer thread.

51 } else {
52 System.out.println("finalizing the test instance");
I would check :
else if (Thread.currentThread().getName().equals("Secondary finalizer")) {
....
else fail(unexpected finalizer thread name)
