Upgrade ParsingUtilities.getClasspath to handle Java 9

[CodesAway]

Java 9 no longer has rt.jar and instead pulls from various modules. Need to update logic to handle this.

Suggested changes

			Path jrePath = Paths.get(useJrePathname, "lib\\rt.jar");

			if (!Files.exists(jrePath)) {
				// Reference: https://github.com/superblaubeere27/obfuscator/issues/63
				// 9/12/2021 - updated to handle changes starting with JDK9
				Path jdkModulePath = Paths.get(useJrePathname, "jmods/java.base.jmod");
				if (Files.exists(jdkModulePath)) {
					jrePath = jdkModulePath;

					addJmods(useJrePathname, classpath, "java.sql.jmod");
				} else {
					throw new IllegalArgumentException("JRE pathname is not a valid JRE directory: " + jrePathname);
				}
			}

			classpath.add(jrePath.toString());

New private helper method addJmods

	private static void addJmods(final String jrePathname, final List<String> classpath, final String... modules) {
		for (String module : modules) {
			classpath.add(Paths.get(jrePathname, "jmods", module).toString());
		}
	}
