Reading passwords stored in WildFly's Elytron credential store using Java?

First forgive my writing in English. The best way i now it's using this code, with library Maven version 1.12.1.Final. Other libraries like the recent Alpha have errors with this code.

<dependency>
        <groupId>org.wildfly.security</groupId>
        <artifactId>wildfly-elytron</artifactId>
        <version>1.12.1.Final</version>
</dependency>
  

Method

public Password giveMeAPass(String alias) throws NoSuchAlgorithmException, CredentialStoreException, InvalidKeySpecException {
    /*
     * Create a ProtectionParameter for access to the store.
     */
    Password storePassword = ClearPassword.createRaw(
            ClearPassword.ALGORITHM_CLEAR,
            "storepass".toCharArray());

    ProtectionParameter protectionParameter = new CredentialSourceProtectionParameter(
            IdentityCredentials.NONE.withCredential(
                    new PasswordCredential(storePassword)));

    Security.addProvider(elytronProvider);

    CredentialStore credentialStore = CredentialStore.getInstance(
            "KeyStoreCredentialStore", csProvider);
    // Configure and Initialise the CredentialStore
    String configPath = System.getProperty("jboss.server.data.dir");
    Map<String, String> configuration = new HashMap<>();
    
    String path = configPath + File.separator + "test.jceks";
    configuration.put("keyStoreType", "JCEKS");
    configuration.put("location", path);
    configuration.put("modifiable", "false");
    
    //Inicialize credentialStore
    credentialStore.initialize(configuration, protectionParameter);

    return credentialStore.retrieve(alias, PasswordCredential.class).getPassword();
}

This method is based on your credential store.

I created the store in a different extension instead of jceks. Once that is fixed, I can able to read the password from the store. Took a while to figure that out because WildFly did not complain while creating the store and all worked fine except reading it programatically.
