Firstly, I put multiple bug reports there to show that 'real programmers' are running into real bugs in the wild. This is necessary because otherwise when I point out bugs, I'm dismissed as a "PL fan" whose ivory tower views don't line up with the mainstream. See elsewhere in the comments.
Secondly, if I click into my first link (2015), it says resolved 2015. And by 'resolved' it means 'duplicate but not fixed'. Because when I clicked into its duplicate, it wasn't 'resolved' until 2018. What did they resolve if tickets are still being filed in 2019 and 2021?
My understanding is that Stream internals are a very complex piece of software that can have multiple different bugs. By the way, I agree with you that eager versions of the Stream methods should also be available directly on the collections.
