As a result, objects previously stored as valid profiles may now throw an IllegalArgumentException during serialization. Discussion about serialization was started in https://github.com/openjdk/jdk/pull/23044 but it seems at the end non-serialization related check was [verified](https://github.com/openjdk/jdk/pull/23044/commits/a5201b5f353e8957a1274261372496768edbc7a2). =(

src/java.desktop/share/classes/java/awt/color/ICC_Profile.java line 1567:

There is possibility for optimization here, because we do not actually need to read the "data" if "csName" is a valid constant for the standard profile. However, the spec does not seem to say anything about the optionality of the data field itself, only about the content of the data. So, I left this part unchanged.
