The modular image no longer contains jar files. The test should use the JRT FileSystem to iterate over the image class files.

Test sun/reflect/CallerSensitive/CallerSensitiveFinder.java need to be re-examined, it tries to check JAR files under jre/lib. The test is passes, but does not actually do anything useful.

        if (classes.isEmpty()) {
            classes.addAll(PlatformClassPath.getJREClasses());
        }
...
    static class PlatformClassPath {
        static List<Path> getJREClasses() throws IOException {
            List<Path> result = new ArrayList<Path>();
            Path home = Paths.get(System.getProperty("java.home"));

            if (home.endsWith("jre")) {
                // jar files in <javahome>/jre/lib
                // skip <javahome>/lib
                result.addAll(addJarFiles(home.resolve("lib")));
