Not able to stop/start/debug remote connected server on IBM OS/400 machine.

[RobertK66]

One of my Liberty development servers runs on an IBM iSeries machine:
os = OS/400 (V7R3M0; ppc) (en_US).
This machine can not be fully controlled via the eclipse open liberty tools.

Am I the first/only one to test this configuration? Or is this a regression because lack of testing possibilities?

For the details of my problem I opened this issue with the OpenLiberty repository because I think the underlying problem is within the server script being aware of OS and having native parts for OS/400 (which do work locally but not over SSH connection).

Looking for some feasible workaround (e.g. prefix all commands with 'qsh -c '), I read some parts of the tools sources here. This ( especially the class: PlatformUtil defaulting to 'LINUX' ) makes me wonder if my usage scenario is a valid use case!?

Is there any chance of configuring/manipulating the commands sent to the servers SSH connection?

Note: My Setup successfully shows the server, the log and config files, makes deployment and - when I do a manual command on the remote servers "A-5250 console" at the right time during eclipse 'start in DEBUG mode', which fails in IDE - I also had a valid and working debug session up and running!
