exceptionCaught DecoderException: javax.net.ssl.SSLHandshakeException: error:1000009c:SSL routines:OPENSSL_internal:HTTP_REQUEST at random time

Expected behavior

the exception throws from the exceptionCaught method,which extends SimpleChannelInboundHandler;

@Slf4j
@Service
@ChannelHandler.Sharable
public class ServerChannelInboundHandler extends SimpleChannelInboundHandler<StompFrame> {

  @Override
  public void channelActive(ChannelHandlerContext context) throws Exception {
    log.info("channel:{} active.", context.channel().id().asLongText());
  }

  @Override
  public void channelInactive(ChannelHandlerContext context) throws Exception {
    log.info("channel:{} inactive.", context.channel().id().asLongText());
    super.channelInactive(context);
  }

  @Override
  public void channelReadComplete(ChannelHandlerContext context) throws Exception {
    context.flush();
  }

  @Override
  public void exceptionCaught(ChannelHandlerContext context, Throwable e) throws Exception {
    **log.error("Unexpected exception occur,channel:{} will be closed, exception is:{} ",
        context.channel().id().asLongText(), e);**
        context.close();
  }
  @Override
  protected void channelRead0(ChannelHandlerContext context, StompFrame stompFrame) throws Exception { ...... }
}

the initializer is:

@Slf4j
@Service
public class WebSocketChannelInitializer extends ChannelInitializer<SocketChannel> {
  @Override
  protected void initChannel(SocketChannel socketChannel) throws Exception {

    ChannelPipeline pipeline = socketChannel.pipeline();
    DomainNameMapping<SslContext> domainNameMapping = sslFactory.newSslContext();
    if (domainNameMapping != null) {
      pipeline.addLast(new SniHandler(domainNameMapping));
    }

    pipeline.addLast("trafficHandler", trafficHandler);
    pipeline.addLast("stompDecoder", new StompSubframeDecoder());
    pipeline.addLast("stompEncoder", new StompSubframeEncoder());
    pipeline.addLast("aggregator", new StompSubframeAggregator(65535);
    pipeline.addLast(eventExecutorGroup, webSocketChannelInboundHandler);
  }
}

@normanmaurer ,but there is no other users to access my code，only myself to access this function，and the error is not occured during my request，it just occured at random time

hi,have you solve it?I meet the same problem

I find the cause why the problem happen. In my project,I config the ssl,but some requests send by http.So errors occur

[normanmaurer]

again if someone is doing http and not https on a port where SSL is used there is not much we can do about.
