JIRA contains a lot of bug reports (410 open bugs) which are probably no longer valid because the bugs have already been fixed. I have looked to a couple of them an most of the bugs were already fixed. I think it would be a good idea to take some time to close the bugs that are either fixed or are really old. I have already commented on a couple of bugs that the bug has already been fixed but only the person(s) responsible for bug management can close the bugs.
Kind regards, Martijn Brinkers
