[drlvm][init] 'java -help', 'java -X' output is very poor
---------------------------------------------------------

                 Key: HARMONY-4069
                 URL: https://issues.apache.org/jira/browse/HARMONY-4069
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
            Reporter: Elena Sayapina


'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:

as applicable.
java [-vm:vmdll -vmdir:dir -D... [-X...]] [args]


'java -X' output on Harmony-r544727:

as applicable.
java [-vm:vmdll -vmdir:dir -D... [-X...]] [args]


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' .
