Test issues with duplicated names (JPRT get impacted, too):

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
