OtherResourcesTest.java is not strictly needed. You should be able to 
provide an appropriate @run tag to OtherResources.java directly, like:

  @run main/othervm --limit-modules=java.base OtherResources

DirPermissionDenied.java
  If you are going to delete the dir, then please use the FileUtils.deleteXXX
  from the test library.

Thanks,
-Chris.
