jtreg failing in awt tests

[Martin Buchholz]

Am I the only one seeing jtreg test failures in latest jdk9/dev, apparently
due to

https://bugs.openjdk.java.net/browse/JDK-8160766

Error: Test clashes with another test with a similar name:
.../jdk/test/java/awt/Focus/DisposedWindow/DisposeDialogNotActivateOwnerTest/DisposeDialogNotActivateOwnerTest.java
 .../jdk/test/java/awt/Focus/DisposedWindow/DisposeDialogNotActivateOwnerTest/DisposeDialogNotActivateOwnerTest.html

(even though I'm not actually running any of the awt tests?)
