UDP I/O Error

[janheuninck]

Hi guys,

I upgraded my test clients written in Java to use the latest Java API (v1.0.4). This however broke the sending and receiving of UDP packages.

After I receive the login event I initialize the UDP channel:

Code: Select all

_smartFox.initUdp(_ip, _port);

I listen to the SFSEvent.UDP_INIT event. Once this event is received, I send the JoinRoomRequest to the server. In the UDP_INIT event I receive the following exception:

Code: Select all

244 [Thread-8] ERROR sfs2x.client.core.sockets.UDPSocketLayer - UDPSocketLayer: General error reading data from socket: org.jboss.netty.buffer.BigEndianHeapChannelBuffer cannot be cast to org.jboss.netty.buffer.TruncatedChannelBuffer

The SFSEvent.UDP_INIT event gets called multiple times as well... I tried compiling with Java SDK 1.6 and 1.7, but both gave the same result.

I'm running the clients on Mac OS X 10.7.5 and both my client (v1.0.4) as server (v2.4.0) are using the latest SmartFox code. The previous Java API I was using (v1.0.1) didn't gave this UDP errors... This API also used netty-3.2.2.Final.jar instead of netty-3.5.7.Final.jar.


Thanks

UPDATE: If I don't upgrade the Netty library to 3.5.7 the UDP seems to work... There must we something wrong with this new library integration.

Unfortunately we checked for all previous issues and didn't expect that new ones would be introduced.
Which seems to be the case

We'll run some more tests and update the release very soon. Meanwhile I think sticking with the previous Netty version is advisable.

Thanks for reporting.
