[jdk11u-dev] RFR: 8222323: ChildAlwaysOnTopTest.java fails with "RuntimeException: Failed to unset alwaysOnTop" [v2]

[Taizo Kurashige]

> Hi,
> 
> This is a backport of JDK-8222323: ChildAlwaysOnTopTest.java fails with "RuntimeException: Failed to unset alwaysOnTop"
> 
> ChildAlwaysOnTopTest.java is not excluded by ProblemList in 11u. But I detected the test failed on Windows Server 2016.
> 
> Also original patch does not apply cleanly to 11u, because the fix uses "StringBuffer.isEmpty()" published in JDK15. I fixed the test so as not to use "StringBuffer.isEmpty()".
> 
> Thanks.
