Here is the platform file that I am using. Hopefully that is the last of the
config files used to remote debug a program.

I added the remote-platform-impl.xml to the git repository for the project so I
can revert the file when netbeans generates a new one. (And I have anther
backup copy, just in case).
I also add the jar files to the project so everything is in one place.

Joao, Here is my complete remote-platform-impl.xml so you can look at
everything. I am using ssh with key key file rather than password to open the
tunnel between the two hosts. So I am using the debug-remote-key rather than
the debug-remote-password
I set a breakpoint in my program and ran netstat on the remote host looking for
the port on the command line. Here is the output. It looks like what you are
describing.

Hi Pat,
There is no other program using the ip port to be used by the debugger. Also
notice that every time you run the program a different port is used... The
issue seems to be related to the tunnel used to connect to the application. In
the remote-platform-impl.xml file we can see
**
This is a smart way for the debugger to connect to the application. First the
remote java application only allows debug connections from the local machine
(notice the address 127.0.0.1:53738 on your example). This is much better from
the security point of view. Second the actual connection to the process being
debugged goes through a tunnel created inside the SSH channel. The issue here
is that the remotetunnel itself is using that same port, hence we get the
"address already in use" error. If we comment the remotetunnel config, the
error is gone but, of course, netbeans fails to connect to the application to
debug it.
Additionally using remotetunnel instead of localtunnel seems to be an
implementation problem. If we are not mistaken NetBeans connects to the
application it wants to debug, and not the other way around. Now, what an ssh
remote tunnel allows us to do is:
"allows anyone on the remote server to connect to TCP port X on the remote
server. The connection will then be tunneled back to the client host, and the
client then makes a TCP connection to port Y on {{{}localhost{}}}. Any other
host name or IP address could be used instead of {{localhost}} to specify the
host to connect to."
[https://ant.apache.org/manual/Tasks/sshsession.html#RemoteTunnel]
[https://www.ssh.com/academy/ssh/tunneling/example#remote-forwarding]
We tried using a localtunnel instead but we have a similar problem:
com.jcraft.jsch.JSchException: PortForwardingL: local port 127.0.0.1:53601
cannot be bound.
[...]
Caused by: java.net.BindException: Address already in use: bind
at java.base/sun.nio.ch.Net.bind0(Native Method)
[...]
We don't understand how you don't have the same issue. Can you confirm that the
following in your "remote-platform-impl.xml" file is as follows:

Jaoa, Here is the complete output from my run with a debugger on a remote

use netstat to determine which processes are using that port.

Fixing remote-platform-impl.xml as suggested "works", but be aware that the
remote-platform-impl.xml file gets recreated if you open an close netbeans.
After this fix we are still not being able to debug our project, we get the
following error (using java 17):
cmd : cd '[...]'; '/usr/java/jdk-17.0.1/bin/java'
-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=127.0.0.1:63890
-Dfile.encoding=UTF-8 -jar [...]/HelloWorld.jar
ERROR: transport error 202: bind failed: Address already in use
ERROR: JDWP Transport dt_socket failed to initialize, TRANSPORT_INIT(510)
JDWP exit error AGENT_ERROR_TRANSPORT_INIT(197): No transports initialized
[open/src/jdk.jdwp.agent/share/native/libjdwp/debugInit.c:734]
Port 63890 is random, and it was not used on remote machine, Debugging always
fails with this error on a new random port, we still don't know why (looking
into it at the moment). Executing the command line directly on the remote
machine has no issue.

I went down the path to figure out what all was necessary to make remote
debugging work.
The scriptdef target in remote-platform-impl.xml needs to look something like
below. Of course the paths to the jar files need to match where they are
installed.
And HelloWorld.properties needs to have the following line added. The
debug-args-line needs to be defined but can be empty.
debug-args-line=
An then the debugger can launch and debug the application on the remote host.
