I tested application using JMeter TCP Sampler. This application closes session
when TCP Socket is closed.

But when I use the isReUseConnection flag - new connection is started
but old socket doesn't closed until JMeter is not closed.

TCPSampler closes connection in the finally block in the "sample" method if isReUseConnection set. But it closes new connection from the map but old connection is never closed.

I think connection should be closed every time when new connection created in the getSocket(). I added closeSocket() method to the getSocket() method:

  ...
  try {    // line 141
	closeSocket();
	con = new Socket(getServer(), getPort());
  ...

and it works for me correctly.

Thank you.
