[12] Review Request: 8210692 The "com.sun.awt.SecurityWarning" class can be dropped

[Sergey Bylokhov]

Hello.
Please review fix for jdk12.

Bug: https://bugs.openjdk.java.net/browse/JDK-8210692
Webrev: http://cr.openjdk.java.net/~serb/8210692/webrev.00
CSR: https://bugs.openjdk.java.net/browse/JDK-8210693

The client code has a "com.sun.awt.SecurityWarning" class which at some 
point in the past, JDK 6u10, was used as a kind of "public" API.

During development of jdk9 it was considered that this API is not 
supported and may be removed in the future: JDK-8051640.
In jdk11 this class was marked as "forRemoval = true" (see JDK-8205588) 
and can be dropped in 12.

In the fix these things were removed:
  - com/sun/awt/SecurityWarning.java
  - The test for SecurityWarning class
  - Test groups, because SecurityWarning is the latest class in 
"com/sun/awt" package
  - The reference to "com/sun/awt" in the "default.policy"

(cc) core-libs-dev:
I am not sure who is responsible to review the change in "default.policy".
