Why do we see JBAS013313 Vault Reader Exception while configuring vault via CLI?

Issue

• Why the cli example mentioned in document section 9.11.4 [1] configure password vault via cli does not work ?

[domain@TestHost:5555 core-service] ls /host==TestHost/core-service
discovery-options  ignored-resources  patching                               
host-environment   management         platform-mbean     
[domain@TestHost:5555 core-service] /host=TestHost/core-service=vault:add(vault-options=[("KEYSTORE_URL" => "test_vaultstore.jceks"), ("KEYSTORE_PASSWORD" => "MASK-pw111111"), ("KEYSTORE_ALIAS" => "vault"), ("SALT" => "12438567"),("ITERATION_COUNT" => "11"), ("ENC_FILE_DIR" => "/jboss-eap-6.3.1/domain/configuration")])
{
    "outcome" => "failed",
    "failure-description" => {"host-failure-descriptions" => [("TestHost" => "JBAS014749: Operation handler failed: JBAS015804: Error initializing vault --  org.jboss.as.server.services.security.VaultReaderException: JBAS013313: Vault Reader Exception:")]},
    "rolled-back" => true
}

• Created the certificate as following:

/keytool -genseckey -alias vault -storetype jceks -keyalg AES -keysize 128 -dname "CN=ABC, OU=Example, L=Washington, ST=TestDistrict, O=TestO, C=US" -keystore /jboss-eap-6.3.1/domain/configuration/test_vaultstore.jceks -keypass "MASK-pw111111" -storepass "MASK-pw111111" -validity 3650
