Bug r29078 broke many Look & Feels (themes) for me

[octo]

Upgrading to r29078 (or r29079) causes many Java Look & Feels (including the one I use, Dracula Contrast) to break for me. Opening the application to the login screen, the L&F has already switched to Metal, and it won't change back to Dracula Contrast, or to any of a bunch of other themes. (But some themes do work.)

The summary for r29078 says "feat: update flatlaf to 3.7.1 by @midgleyc in #3529". Flatlaf is L&F stuff, and it's going from 1.6.5 to 3.7.1, which sounds like a big jump, so, yeah, probably unsurprising.

If it helps, my OS is Windows 11, and my openjdk version is "25.0.3" 2026-04-21 LTS.

Thanks, all.

Alright, let me check what happened. I use Arc, which went through fine, and I clicked on a few others and they all worked, so I'll see what's happening here.

Okay, basic check: Dracula works (changes the skin), Dracula Contrast does nothing.

Seems to be a rename in 3.6: https://github.com/JFormDesigner/Fl...hemeuilite from Flat<theme> to FlatMT<theme>.

A bunch of others have also been broken.

"Material" themes have moved classes (in 3.6) and will be fixed.

"Contrast" themes have been removed entirely without replacement (in 3.2). Evidently not using semver there...

Gruvbox Dark Medium and Soft were also removed at the same time.
