Subject [jira] Commented: (HARMONY-4069) [drlvm][init] 'java -help', 'java -X' output is very poor
Date Fri, 15 Jun 2007 12:36:27 GMT

    [ https://issues.apache.org/jira/browse/HARMONY-4069?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12505208
] 

Eugene S. Ostrovsky commented on HARMONY-4069:
----------------------------------------------

It seems that patch for HARMONY-3876 committed in r542499 is incorrect.
It makes launcher to check for -help and -X options, print short usage message and exit without
creating VM. Thus VM is unable to print it's detailed information for these options.

> '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:
> Harmony Java launcher
> Apache Harmony Launcher : (c) Copyright 1991, 2006 The Apache Software Foundation or
its licensors,
> as applicable.
> java [-vm:vmdll -vmdir:dir -D... [-X...]] [args]
> 'java -X' output on Harmony-r544727:
> Harmony Java launcher
> Apache Harmony Launcher : (c) Copyright 1991, 2006 The Apache Software Foundation or
its licensors,
> 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' .
