    Force printing of system.out.printf message (#10658)
    
    * Force printing of system.out.printf message
    
    printf writes into a buffer that will not print instantly. Even worse IDE terminals will ignore System.out.flush() calls.
    
    See https://stackoverflow.com/questions/9852705/java-printf-not-printing#comment12559175_9852740
    
    I used IntelliJ (most recent version from 2021) and thought something was broken or unreasonably slow.
    
    * Fix typo
    
    * Use println instead of printf
