The desktop module provides the `ICC_Profile` class used in Color Management for image processing applications. Previously, an `ICC_Profile` instance would always allow an application to modify the raw color profile data which the `ICC_Profile` encapsulates. However, instances of this class provided by the desktop module itself are shared and should never be modified. JDK now enforces this restriction on these shared instances. As a result, application code which tries to do this will cause an exception to be thrown.
