Description asenk 2011-09-20 12:01:33 UTC 
Product Version: NetBeans IDE Dev (Build 201109190600)
Java: 1.7.0; Java HotSpot(TM) Client VM 21.0-b17
System: Linux version 2.6.38-11-generic running on i386; UTF-8; en_US (nb)
User directory: /home/tester/.netbeans/dev
Cache directory: /home/tester/.netbeans/dev/var/cache

When I use "--list-groups" options, my groups are printed into standard output, but the IDE starts.

I think that this switch should work somehow as "--help" switch. That means, that groups will be printed into standard output, and IDE will not start. Then I can choose some Project Group and start IDE with "--open-group NAME" option.

As far as I know this is impossible given the sendopts API. See bug #168556 comment #14. If I throw new CommandException(0) at the end of GroupOptionProcessor.process with LIST_OPTION, and the IDE _is_ running, the output shows the ugly

Error code: 0
Ignored unknown option: --list-groups

and anyway the full module system is started with all accompanying messages. Basically you cannot add a module-supplied option which avoids starting the full application. (org.netbeans.modules.sendopts.Handler also uses WHEN_EXTRA, not WHEN_BOOT, and --help is anyway hardcoded in core.)
