Yes.  Since it was decided not to export com.sun.awt API (JDK-8051640), 
they are no longer supported.  Is there a CSR filed officially declaring 
com.sun.awt APIs are no longer supported? Since it's already deprecated 
for removal, it may be worth to have a release note for JDK-8205588 if 
we didn't officially declare it unsupported.
