<AWT Dev> [8u-backport] RFR: 8166673: The new implementation of Robot.waitForIdle() may hang

[Fairoz Matte]

Hi,

Please review the backport of "JDK-8166673: The new implementation of Robot.waitForIdle() may hang" to 8u
Changes apply cleanly, there was a typo error in test case name "WaitForIdleSyncroizedOnString.java" it has been corrected to "WaitForIdleSynchronizedOnString.java"
As the test case doesn't have any impact on JDK8, it passes before the patch.
I have verified the issue by executing test case found in one of the duplicate issue JDK-8194862
