Archive PLATFORM class and override with --upgrade-module-path. * 2. Archive PLATFORM class and override with -p. * 3. Archive APP class and override with --upgrade-module-path. * 4. Archive App class and override with -p. * For all 4 tests, the class is instantiatied and toString() is called * to check whether the archived version or the override version was instantiatied. * For tests 1 and 3, the overridden version should be instantiatied. * For tests 2 and 4, the archived version should be instantiated. * * This test uses the same test helper class in all 4 cases. It is located in * src/test/jdk/test/Main.java. It will be invoked once for each test cases, * with parameters to the test determining how it is run and what the * expected result is. See Main.java for a description of these 3 arguments. */ import java.io.File; import java.nio.file.Files; import java.nio.file.Path; import java.nio.file.Paths; import jdk.test.lib.Asserts; import jdk.test.lib.cds.CDSOptions; import jdk.test.lib.cds.CDSTestUtils; import jdk.test.lib.process.OutputAnalyzer; import jdk.test.lib.process.ProcessTools; public class OverrideTests { private static final String TEST_SRC = System.getProperty("test.src"); private static final Path SRC_DIR = Paths.get(TEST_SRC, "src"); private static final Path MODS_DIR = Paths.get("mods"); // the module that is upgraded private static final String[] UPGRADED_MODULES = {"jdk.compiler", "java.net.http"}; private static final Path[] UPGRADEDMODS_DIR = {Paths.get("upgradedmod1"), Paths.get("upgradedmod2")}; // the test module private static final String TEST_MODULE = "test"; private static final String MAIN_CLASS = "jdk.test.Main"; // test classes to archive.
