It seems the priority for annotation from a visual point of view is too much. When you look at the code (A hibernate entity class for example) the annotations tries to steel your attention too much since they are both bold and italic. My suggestion would be to make them none italic and bold. The same goes for abstract class as well where the abstract class tries to steel the attention when you look at a class.
Another thing i notice is if i try to change this values from preference and they get reset back after a restart. Color changes are preserved some times as i have observed.
Thank you for the screenshots. I see the problem with annotation/abstract styling at my end. I have filed a bug for the dev team to work on the styling issues. We will keep you posted when the fix is out.
