I think Sergey's changes are okay.

The main issue with com.sun.awt API is that it tried to be both an 
exported and internal/unsupported API at the same time (it's javadoc 
reads "This class is an implementation detail and only meant for limited 
use outside of the core platform"). This doesn't work for modules. In 
addition the design principles in JEP 200 make it clear that standard 
modules should not export a non-standard package to all modules. If 
there has been extensive use of this API then I could imagine it being 
refactored and moved into a JDK-specific module but there was little 
evidence of usage. So where we ended up in JDK 9 is that the API is not 
exported. This means, as Mandy hinted, you can't compile against this 
API (at least not without --add-exports to the compiler). Existing code 
using this API will continue to run on JDK 9, 10, 11 or until the 
java.desktop module is fully encapsulated or the SecurityWarning class 
is removed. Sergey got there first.
