Netty server is incompatible with ObjectOutputStream on the client side

Recently I faced with the following problem while playing with Netty:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

io.netty.handler.codec.TooLongFrameException: Adjusted frame length exceeds 1048576: 2901213193 - discarded at io.netty.handler.codec.LengthFieldBasedFrameDecoder.fail(LengthFieldBasedFrameDecoder.java:493) at io.netty.handler.codec.LengthFieldBasedFrameDecoder.failIfNecessary(LengthFieldBasedFrameDecoder.java:469) at io.netty.handler.codec.LengthFieldBasedFrameDecoder.decode(LengthFieldBasedFrameDecoder.java:404) at io.netty.handler.codec.serialization.ObjectDecoder.decode(ObjectDecoder.java:68) at io.netty.handler.codec.LengthFieldBasedFrameDecoder.decode(LengthFieldBasedFrameDecoder.java:351) at io.netty.handler.codec.ByteToMessageDecoder.callDecode(ByteToMessageDecoder.java:231) at io.netty.handler.codec.ByteToMessageDecoder.channelRead(ByteToMessageDecoder.java:131) at io.netty.channel.DefaultChannelHandlerContext.invokeChannelRead(DefaultChannelHandlerContext.java:372) at io.netty.channel.DefaultChannelHandlerContext.fireChannelRead(DefaultChannelHandlerContext.java:357) at io.netty.channel.DefaultChannelPipeline.fireChannelRead(DefaultChannelPipeline.java:780) at io.netty.channel.nio.AbstractNioByteChannel$NioByteUnsafe.read(AbstractNioByteChannel.java:99) at io.netty.channel.nio.NioEventLoop.processSelectedKey(NioEventLoop.java:497) at io.netty.channel.nio.NioEventLoop.processSelectedKeysOptimized(NioEventLoop.java:465) at io.netty.channel.nio.NioEventLoop.run(NioEventLoop.java:359) at io.netty.util.concurrent.SingleThreadEventExecutor$2.run(SingleThreadEventExecutor.java:101) at java.lang.Thread.run(Thread.java:745)

How to insert code blocks in Blogger posts

I didn’t find any setting which would allow me to insert code blocks in Blogger posts but I managed to overcome this problem.

Here’re two simple and handy online converters of code to html:

markup
pros: language auto-detection, small html in the output
cons: no line numbers support, no horizontal scrolling
styles I liked: Slush & Poppies, iPlastic

hilite.me
pros: line numbers support, horizontal scrolling in case of long lines
cons: big html in the output
styles I liked: friendly, default, colorful
CSS I used: border:none;

Let’s say we have the following piece of code which is desirable to insert as a code block:

public class RowSocketClient {

    public static void main(String[] args) throws Exception {
        String host = "localhost";
        int port = 4446;

        try (Socket socket = new Socket(host, port);
                ObjectOutputStream out
                    = new ObjectOutputStream(socket.getOutputStream())) {
            out.writeObject("ping");
        }
    }
}
