    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.
