使用FST或者Kyro序列化，当服务的方法参数含有Java原生数据类型时，就会出错 about dubbox

无法重现此问题

[xiaolongyuan]

这种问题序列化时我也经常遇见

[baoyinli]

这个可能是Kyro的问题

可以重现呀。环境是JDK7。在远程方法调用时就会出现。配置改成hessian2，就一切正常。
查了一下，当服务的方法参数含有Java原生数据类型时（比如int，long等），com.alibaba.dubbo.rpc.protocol.dubbo.DubboCodec类中的encodeRequestData方法中 标记有 // NOTICE modified by lishen 的部分会跳入out.writeInt(-1);，导致后续解码的时候出错。

你可以发个可以重现的代码

我也遇到了，偶尔还遇到 Caused by: com.esotericsoftware.kryo.KryoException: Encountered unregistered class ID:xx
发现kryo还是有些坑的，之计修改使用默认的序列化协议了

e.g.
String doSomething(String type, int num);

已修正
