The command line options are not handled optimally by Hudson. Here are a few observations:

• There are no short option names.
• Invalid option names are not flagged. It remains to be seen if incorrect options should be ignored (falling to defaults) or startup should be aborted.
• A single - is not a valid long option name. User should be notified of that.

It's better to keep the Hudson startup options standard, documented and not dependent on underlying web container.
