<AWT Dev> [15] Review Request: 8237049 Rollback the workaround for JDK-4533057

[Sergey Bylokhov]

Hello.
Please review the fix for JDK 15.

Bug: https://bugs.openjdk.java.net/browse/JDK-8237049
Fix: http://cr.openjdk.java.net/~serb/8237049/webrev.00

Long-time ago we added a workaround(JDK-4280257 [1]) for
the bug in the java plugin(JDK-4533057 [2]).

Since the the plugin was dropped and the bug is not
reproducible any more we can delete the workaround as well.
