that is great.
to do that, you need to agree on the contributors agreement: http://jira.jboss.com/jira/browse/JBLAB-64?page=comments
we grant cvs access very easily. you only need to show that you have a clue. e.g. by explaining how you added that collection support, posting the changed fragments here in the developers forum (http://www.jboss.com/index.html?module=bb&op=viewforum&f=219) or by sending me the code you wrote.
does it include some tests ?
regards, tom.
no tests, no beer and lots of hail mary's
