Settings in [Preferences > Java > Editor > Syntax Coloring] are not saved when Eclipse Dark theme is enabled.

To reproduce:

Am i doing something wrong? I basically wasted this evening trying to make the settings stay. Even manually editing workspace\.metadata\.plugins\org.eclipse.core.runtime.settings\org.eclipse.jdt.ui.prefs does not work because of CSS override.

Maybe you recorded the preferences settings in the past and they are being re-applied each time you start any workspace? Some details are here:

Of course if it really is the CSS ignoring the preferences that sounds like a bug to me. But even then, you could consider contributing the improvements/fixes for the CSS:

I reinstalled Eclipse multiple times with different versions (2022-12 and 2020-06) with multiple JREs (19.0.1 - 1.8)

I was afraid the workspace directory was left in a dirty state so i deleted the folder everytime before making any new attempt.
Never managed to disable Syntax coloring in Java Editor Preferences.

If you disable Themes in General > Appearance, disabling Syntax coloring works correctly every time.

As an update:
Changes in colors in [Preferences > Java > Editor > Syntax Coloring] work correctly. Changes in Enabled/Disabled state won't stick and are reset when you restart Eclipse when Dark Theme (or themes in general) in enabled
