Is redirected stdout/stderr buffered in install4j?

I'm using install4j to generate Windows executables.
The launcher is configured to redirect stderr and stdout to log\error.log resp. log\output.log.
This all works as intended, the log files are written in the expected location and with the expected content.

However, I do not know whether output is flushed or buffered.
I.e. if I kill the program via the Task Manager, can I expect to see the last line that was printed to stderr, or can I expect to lose some output?
(Both outcomes would be fine, I just need to know what will happen so I known how to interpret the log files I'm getting, and what to ask of customers to make sure that I get complete logs.)

The redirection files are flushed for every newline, but not for every character.
