Cannot use NettyAsyncHttpProvider

[johngray]

Hello.

I have the following sample code:

   AsyncHttpClient asyncHttpClient = new AsyncHttpClient();

    try {

        final Response response = asyncHttpClient.prepareHead(getFullUrl(filePath)).execute().get();

        return response.getStatusCode();

    } catch (Exception e) {

        return 0;
    }

And it gives the following log output:

DEBUG com.ning.http.client.providers.netty.NettyAsyncHttpProvider: Number of application's worker threads is 8
DEBUG com.ning.http.client.providers.netty.NettyAsyncHttpProvider:

And after some time (during debugging session), this:

DEBUG com.ning.http.client.providers.netty.NettyAsyncHttpProvider: Unexpected I/O exception on channel [id: 0x2f33cbcc, /127.0.0.1:52679 :> localhost/127.0.0.1:8080]

And the last line is repeated several times.

The problem is, when I change provider to JDK everything works fine. But I cant use JDK provider because I wiil neen to upload really large files using the client and sun`s UrlConnetcion class is limited in this matter to approximetely 2GB.

Can somebody provide any help on this?

I am using Netty 3.4.3

OK filled

https://github.com/netty/netty/issues/315

Can you try with 3.4.4.Final and see if the issue has been fixed? Also please add your OS and the JDK version. Thanks

[johngray]

Linux 3.3.4-2-ARCH kernel

java version "1.7.0_04"
Java(TM) SE Runtime Environment (build 1.7.0_04-b20)
Java HotSpot(TM) 64-Bit Server VM (build 23.0-b21, mixed mode)

I tried with 3.4.4 and now everything works!
I am dumb, everything I was need to do is just to check the lattest netty version. :)
Thanks. I hope this bug report will be valuable anyway.

Thanks for the fast response. This bug is valuable and validated that the bug was fixed between 3.4.3 and 3.4.4. Thanks!
