Hello. Please review the fix for jdk 12. This class was used as a headless toolkit for embedded purposes. - It was added in the JDK-7030063 - Its usage was removed in JDK-8140723 and JDK-8025673.
The usage of strings "sun.awt.HToolkit" and "javaplugin.version" in GraphicsEnvironment were also dropped, because both are never use.
Bug: https://bugs.openjdk.java.net/browse/JDK-8210286 Webrev: http://cr.openjdk.java.net/~serb/8210286/webrev.00 -- Best regards, Sergey.
