Protostuff 如何序列化Class?

Question

/*Protostuff 序列化泛型类*/
Page<User> pageUser = new Page<User>();
private RuntimeSchema<Item> schema = RuntimeSchema.createFrom(pageUser .class);//这里就不行了

byte[] array=ProtostuffIOUtil.toByteArray(item,schema,
LinkedBuffer.allocate(LinkedBuffer.DEFAULT_BUFFER_SIZE));

/*Protostuff 无法序列化泛型类*/
System.out.println("序列化数据为"+array);

/*异常信息*/
Exception in thread "main" java.lang.RuntimeException: Reading from a byte array threw an IOException (should never happen).
