commit 1d7b5ed74f6f38a5ea47ebd812eaaa39511a8472
Author: JB Onofré <jbono...@apache.org>

    fix(shell): enable autoFlush on console PrintStream (#2267) (#2518) (#2538)
    
    System.out.print() without a newline was not displayed immediately on
    the Karaf console because the PrintStream wrapping the terminal output
    was created without autoFlush. Enable autoFlush on the local console
    and SSH command PrintStreams, consistent with ShellFactoryImpl.
