CSR Review Request, JDK-8218932 Remove the internal package com.sun.net.ssl

[Xuelei Fan]

Hi,

Could I get the CSR reviewed:
    https://bugs.openjdk.java.net/browse/JDK-8218932

The internal package com.sun.net.ssl had been deprecated since JDK 1.4, 
and was not exported in the java.base module since JDK 9.  Application 
cannot use them directly now.  It should be safe to remove them in JDK 13.

If you are using the internal package for some reason, please let me 
know the compatibility impact by the end of Feb 20, 2019.

Thanks,
Xuelei
