RFR: 8076090: jimage extract + recreate broken again

[Jim Laskey (Oracle)]

Thanks Mandy.  Changed the main to ;

    public static void main(String[] args) {
        final String JAVA_HOME = System.getProperty("java.home");
        Path jimagePath = Paths.get(JAVA_HOME, "bin", "jimage");
        Path bootimagePath = Paths.get(JAVA_HOME, "lib", "modules", "bootmodules.jimage");

        if (Files.exists(jimagePath) && Files.exists(bootimagePath)) {
            String jimage = jimagePath.toAbsolutePath().toString();
            String bootimage = bootimagePath.toAbsolutePath().toString();
            String extractDir = Paths.get(".", "extract").toAbsolutePath().toString();
            String recreateImage = Paths.get(".", "recreate.jimage").toAbsolutePath().toString();

            exec(new String[] {jimage, "extract", "--dir", extractDir, bootimage});
            exec(new String[] {jimage, "recreate", "--dir", extractDir, recreateImage});

            System.err.println("Test successful");
         } else {
            System.err.println("Test skipped, no module image");
         }
    }

Running jprt - okay to push after that?

Cheers,

-- Jim
