38 * This test consists of 4 tests: |
|
39 * 1. Archive PLATFORM class and override with --upgrade-module-path. |
|
40 * 2. Archive PLATFORM class and override with -p. |
|
41 * 3. Archive APP class and override with --upgrade-module-path. |
|
42 * 4. Archive App class and override with -p. |
|
43 * For all 4 tests, the class is instantiatied and toString() is called |
|
44 * to check whether the archived version or the override version was instantiatied. |
|
45 * For tests 1 and 3, the overridden version should be instantiatied. |
|
46 * For tests 2 and 4, the archived version should be instantiated. |
|
47 * |
|
48 * This test uses the same test helper class in all 4 cases. It is located in |
|
49 * src/test/jdk/test/Main.java. It will be invoked once for each test cases, |
|
50 * with parameters to the test determining how it is run and what the |
|
51 * expected result is. See Main.java for a description of these 3 arguments. |
