  42  * These tests will verify that AppCDS will correctly handle archived classes
  43  * on the classpath that are in a package that is also exported by the jimage.
  44  * These classes should fail to load unless --limit-modules is used to hide the
  45  * package exported by the jimage. There are 8 variants of this test:
  46  *   - With a jimage app package and with a jimage ext package
  47  *   - With --limit-modules and without --limit-modules
  48  *   - With AppCDS and without AppCDS (to verify behaviour is the same for both).
  49  *
  50  * There is also a 9th test to verify that when --limit-modules is used, a jimage
  51  * class in the archive can be replaced by a classpath class with the
  52  * same name and package.
