RFR: 8063102: Change open awt regression tests to avoid sun.awt.SunToolkit.realSync, part 1

[Hohensee, Paul]

Please review this test backport. It’s part of the sequence described by https://mail.openjdk.java.net/pipermail/jdk8u-dev/2020-November/012959.html.

Original JBS issue: https://bugs.openjdk.java.net/browse/JDK-8063102
Original commit: http://hg.openjdk.java.net/jdk9/jdk9/jdk/rev/beec47aecf5a
IcedTea8 commit: http://icedtea.classpath.org//hg/icedtea8-forest/jdk?cmd=changeset;node=13df749e77d4<http://icedtea.classpath.org/hg/icedtea8-forest/jdk?cmd=changeset;node=13df749e77d4>
Webrev: http://cr.openjdk.java.net/~phh/8063102/webrev.8u.jdk.00

The webrev is identical to the IcedTea8 commit.


test/java/awt/security/WarningWindowDisposeTest/WarningWindowDisposeCrashTest.java and test/java/awt/security/WarningWindowDisposeTest/WarningWindowDisposeTest.java

were modified by the original patch but do not exist in jdk8, and were therefore removed.



Thanks,

Paul
