Recently I had problems with SVC-3017 (now 4 years old so clearly not a priority to be fixed) but by finding it in the JIRA I was able to design my script to take account of it.
Without being able to look this up it would have taken me hours of frustrating script checking, trying to figure out what I had done wrong, before I'd even realise it was a bug.
Then more time to work out a foolproof reproduction so that it didn't just get closed “unable to reproduce”, apparently with no reply allowed.
And then it would get closed as a duplicate anyway...
The point is that this happens really often. The JIRA is an important resource.
Now there will be no sharing of knowledge about bugs and workarounds with residents. That's fine if bugs were a rarity and fixed quickly, but there are lots bugs and many stay open for years. Trying to hide them is just stupid.
