Spring TCP Socket client not receiving data from Mainframe

Question

I am trying to use this example to send and receive the data to and from a Mainframe machine that uses HEX data to communicate. So I have the following in my config

Answer 1

If the mainframe doesn't close the connection at the end of the response, as it probably doesn't, the read loop will never exit. The loop needs to be aware of the expected or actual length of the response somehow.

The serializers also surely need to do some EBCDIC conversion?
