I should probably write a comment about this. Basically, when I was using releases/2024-03 from below, I noticed jdt.core.manipulation would get used from there, even though the one in I-builds was newer. When I bumped to 2024-06, it went away. Bumping to 2024-09 had the issue come back. I decided it makes perfect sense to explicitly require jdt.core.manipulation and that seems to resolve it.

retest this please. 403s everywhere 😐 .

Update: First time I've seen it in the build system.
