is it possible to reconfigure the JNPMService with a new password value?

Basically I am using JNPM to programatically pull down a npm module so I can use some of its files.

if for some reason the file i'm looking for is deleted I want JNPM to pull it down again when the code executes. So I tried something like this.

if(!script_file.exists()){
            JNPMSettings defaultrepo = JNPMSettings.builder()
                .homeDirectory(Paths.get(homePath)) //Optional
                .downloadDirectory(Paths.get(downloadPath)) //Optional
                .installDirectory(Paths.get(installPath))
                .username(config.NPMJS_Username()).password(config.NPMJS_Access_Token())
                .registryUrl(config.NPMJS_Repo_URL())
                .httpLoggerLevel(HttpLoggingInterceptor.Level.BASIC)
                    .build();
            logger.error(String.format("JNPM Configured Password %s", defaultrepo.getPassword()));
            if (!JNPMService.isConfigured()){
                JNPMService.configure(defaultrepo); // maybe the service should be static? can I do that or something?
            }
            else if (!JNPMService.instance().getSettings().getPassword().equals(config.NPMJS_Access_Token())){
                logger.error(String.format("Old PWD: %s New PWD: %s", JNPMService.instance().getSettings().getPassword(),config.NPMJS_Access_Token()));
                JNPMService.configure(defaultrepo);
            }
}

I was hoping I could reconfigure the instance with an updated password, but it seems that the service does not allow for a reconfiguration based on what I am seeing.

public static synchronized JNPMService configure(JNPMSettings settings) {
		if(isConfigured()) throw new IllegalStateException("You can't configure JNPM twise: it's already initiated");
		try {
			settings.createAllDirectories();
			settings.getLogger().log("Settings: "+settings);
			instance = new JNPMService(settings);
			return instance;
		} catch (Exception e) {
			settings.getLogger().log("Can't configure JNPM due to problems with settings", e);
			return null;
		}
	}

So the only way to reconfigure it would be to restart the whole Java program.

That's good question... Under the hood there is the following default static method:

JNPM/jnpm/src/main/java/org/orienteer/jnpm/JNPMService.java

Lines 81 to 85 in e90988b

	static JNPMService instance(JNPMService substitution) {
	JNPMService preserved = instance;
	instance = substitution;
	return preserved;
	}

You can call it through reflection. I do understand that it's dirty, but that's the only method I can propose so far without changes.
