Problem executing SampleListener

[Ivo-Balbaert]

The program doesn't work for me. I can start it up, and the server starts with the message:
Started server at port 9092
Then I open other another terminal window, and try to connect with telnet or netcat (nc) like this:
nc 127.0.0.1 9092
However, a connection is not established or if there is one, it is immediately disrupted.
Nothing is echoed or printed to the console, but I also do not see any error messages.
The server window just stays open, until it is closed or via CTRL+C.
I am testing on Windows 10 with Beef 0.42.7
Any idea what could be the problem, or what I am doing wrong?
Thanks!

Hi, try to clean solution (clean all), rebuild the workspace, and run it again.
I'm not having any issue, i tested with jMeter. You can see it working opening the server address in a browser.

I did the clean all, haven't tried jMeter yet.

When I open a browser with localhost:9092, I get a ERR_SOCKET_NOT_CONNECTED, nothing in server console
However when I debug this, I see a connection and the following text appears in the server console:

GET / HTTP/1.1
Host: localhost:9092

Failed to receive data from socket

Trying to open a telnet connection:
Microsoft Telnet> o localhost 9092
Connecting To localhost...

// After a few seconds:
Could not open connection to the host, on port 9092: Connect failed
or
Connection to host lost.

In the debugger, mHandle seems to be INVALID_SOCKET

Changing the port number doesn't help.

jMeter sends hundreds of requests per second, but a manual connection doesn't seem to get through in the code.
Thanks for looking into this.
