NullPointerException when using single Conjur instance to retrieve multiple secrets

[derekjwashington]

When running the following test I receive the exception below. I am attempting to retrieve multiple secrets from a single Conjur instance. My goal is to inject a Conjur singleton into a class for parsing a config file that contains references to Conjur secrets.

If I instantiate Conjur each time I retrieve a secret then the test succeeds

    @Test
    public void getMultiple() {

        System.setProperty("CONJUR_ACCOUNT", "cloud");
        System.setProperty("CONJUR_AUTHN_LOGIN", "host/configuration-service");
        System.setProperty("CONJUR_AUTHN_API_KEY", "3c4gtv62qeprhbyedben2t4pa6s3jj5q8y12t356s3nzxtxg2vh8yrw");
        System.setProperty("CONJUR_APPLIANCE_URL", "http://localhost:8080");
        Conjur conjur = new Conjur();
        String username = conjur.variables().retrieveSecret("mongo/username");
//        conjur = new Conjur();
        String password = conjur.variables().retrieveSecret("mongo/password");
        System.out.format("%s/$s\n", username, password);
    }
