Are you going to mitigate the lack of active developers for Openfire by creating a bunch of overlapping, duplicating tickets? I'm going to ask to remove your JIRA access then.. Most of them are not bugs even. Also, why adding all the not existing 3.9.0, 4.0.0 version etc., if you can't know when those "bugs" will be fixed?
This seems like a collection of 3 bugs, so it could be a super task with 3 child tasks. But i see no point to have one. They are only somewhat related. Fixing those 3 bugs won't make Openfire 100% secure, just a little bit more secure.
