Indeed, it *can be*, and I prefer this design. This way, the `isBuiltIn` field can't be changed after the object is constructed. I think it's a cleaner design.

To achieve this, you have to add a constructor which accepts a boolean flag: `ICC_Profile(ProfileDeferralInfo pdi, boolean builtIn)`, and `ICC_ProfileRGB` and `ICC_ProfileGray` need to provide an additional constructor as well.

Here's [a diff to your branch which achieves this](https://github.com/honkar-jdk/jdk/compare/BuiltInCheck...aivanov-jdk:jdk:harshitha/8346465-built-inprofiles).

When [you compare the changeset that I propose to `jdk/master`](https://github.com/openjdk/jdk/compare/master...aivanov-jdk:jdk:harshitha/8346465-built-inprofiles), there are less differences, and `BuiltInProfile` remains an interface. Yet two more files `ICC_ProfileRGB` and `ICC_ProfileGray` are modified.
