the Exception like this Caused by: java.lang.NullPointerException at java.util.HashSet.add(HashSet.java:219) at com.esotericsoftware.kryo.serializers.CollectionSerializer.read(CollectionSerializer.java:134) at com.esotericsoftware.kryo.serializers.CollectionSerializer.read(CollectionSerializer.java:40) at com.esotericsoftware.kryo.Kryo.readObject(Kryo.java:731) at com.esotericsoftware.kryo.serializers.ObjectField.read(ObjectField.java:125

when debug the code,i found the result of kryo.newInstance(type) (CollectionSerializer#111 )is null，so why this happen? the HashSet doesn`t support kryo sede?
