Someone got a wild hair to move everything to Confluence (and Jira) at work. Much like the move to Git, this seems to be largely because they’re hiring people who don’t know how to work with anything else and refuse to learn.
It’s a Java app, and the minimum heap size they require is 1 GB. This turns out to be barely enough to handle maybe three users and a tiny handful of pages, because the app has now locked up completely twice due to garbage collection. I doubt we have more than 20 MB of data in the damn thing so far, so this is just really badly written.
