commit 99c81bc0bc7a67b69e1575ee869877d8609cbd37
Author: JB Onofré <jbono...@apache.org>

    fix(shell): enable autoFlush on console PrintStream (#2267) (#2518)
    
    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.
