Let's make sure issue is not already fixed in latest builds first.
Steps to reproduce
From a fresh installation and clean workspace:
Light & Default

Looks the same as Light & Classic (changed the pref and restarted Eclipse):
I expected: Classic to have round corner on tab headers and a bit more contrastive colors.
But got: Classic looking the same as Default
Here is some relevant log output
Not sure what to look for in <workspace>/.metadata/.log. Please advise.
Tested under this environment:
- OS & version: KDE Plasma@Linux
- Eclipse IDE/Platform version (as shown in Help > About): 4.40.0.20260604-0652
