While testing I received a NoSuchMethodError on ConcurrentHashMap$KeySetView:
java.lang.NoSuchMethodError: java.util.concurrent.ConcurrentHashMap.keySet()Ljava/util/concurrent/ConcurrentHashMap$KeySetView The reason is that Java 1.7 ConcurrentHashMap#keySet() returns a Set<K> while the 1.8 ConcurrentHashMap#keySet() returns a ConcurrentHashMap.KeySetView<K,V>. I'll create new one using Java 1.7. Also, if you have any good idea for this, Pls let me know. -- Best Regards, Edward J. Yoon -----Original Message----- From: Edward J.
