Test clashes with another test after JDK-8160766

In attempt to run JTREG for any test I have a message:
Error: Test clashes with another test with a similar name:
  ...test/java/awt/Focus/DisposedWindow/DisposeDialogNotActivateOwnerTest/DisposeDialogNotActivateOwnerTest.java
  ...test/java/awt/Focus/DisposedWindow/DisposeDialogNotActivateOwnerTest/DisposeDialogNotActivateOwnerTest.html

and the exit code for the JTREG run isn't 0. It's 5.
