HI @amaembo, thanks for taking a look at this.

I think you should be careful here, and ask is introducing the enchanced switch 
adding any value? While I think the enchanced switch can be valuable when it 
makes the code more readable, it shouldn't be introduced just for the sake of 
using it.

src/java.base/share/classes/java/util/PropertyPermission.java line 337:

> 337:         return switch (mask & (READ | WRITE)) {

Just a suggestion, but it might be more readable if you align the lambda 
operators
