Description
'java -help', 'java -X' output is very poor in comparison with RI.
Help options give very little information and it make worse Harmony usability.
It looks like existing print_generic_help() and print_help_on_nonstandard_options() from vmcore/src/init/parse_arguments.cpp are not used.
'java -help' output on Harmony-r544727:

Similar issue HARMONY-3876 was closed recently,
but it looks like it was partially fixed: only returning value was corrected.
Please, see also HARMONY-3409 concerning 'java -XX' .
