@tstuefe As you say, there are situations where we can solve with the tee command, but only if java is invoked as a shell command. In the case of an application server, it is difficult to redirect to the tee command because java is started as a subprocess of the administration service.

Another reason is that the tee command does not exist in every environment where java runs. In a windows environment, we cannot use features like the tee command without adding features like wsl or cygwin.

I'm not proposing complex features outside the Unix philosophy, I'm just suggesting a way to enable options that are currently mutually exclusive.
