     * will be fixed in next hazelcast version (1.9.3). Mail from Talip (21.02.2011):
     * 
     * I see. Hazelcast.shutdownAll() should cleanup instances (maps/queues). I just fixed it.
     * 
     * AtomicNumber.destroy() should also destroy the number and if you call atomicNumber.get() after the destroy it should throw IllegalStateException. It is also fixed.
     * 
     * set test to true by default. TODO: if we'll get the new hazelcast version I'll fix the test.
