<AWT Dev> [9] Review Request: 8066005 java.awt.event.KeyEvent.originalSource doesn't have "since" tag in Serialized Form

[Sergey Bylokhov]

Hello,
Please review the fix for jdk9.

In the jdk_8_RI the new private field was added to the KeyEvent class(it implements Serializable), but it was not marked as @since 1.8.
In the fix the @since tag was added. Note that later this field was leaked to the jdk7u80 but I suppose we should not mark it as @since 1.7?
