Java Google Photos Api - How to cancel 'PhotosLibraryClient.initialize(settings)'?

I am developing an app in Java (Kotlin :X) that uses the Google Photos Api.
I am stuck in a flow where I may want to cancel the current client initialization attempt and try again.
val settings = PhotosLibrarySettings.newBuilder()
.setCredentialsProvider(
FixedCredentialsProvider.create(
getUserCredentials(credentialsPath, SCOPES, email)
)
)
.build()
// let the Thread hanging until a successful initialization :/
return PhotosLibraryClient.initialize(settings)
But unfortunately, I did not find any way to do this besides enveloping the PhotosLibraryClient.initialize(settings) call in a Thread and calling the deprecated method Thread#stop().
If I do this call twice (on different threads), without successfully stopping one of the client initializations, the following exception is thrown: java.io.IOException: java.net.BindException: Address already in use (Bind failed).
How can I successfully stop a client initialization attempt without calling Thread#stop()?

Problem Implementing a custom Keycloak Authenticator SPI

I'm trying to implement a custom keycloack Authenticator SPI for authentication purposes against an external Identity provider. The users already exist on the keycloak store, I only need connection to the custom SPI to authenticate them.
I'm following section 8.3 of the official guide https://www.keycloak.org/docs/latest/server_development/index.html#_auth_spi_walkthrough, which is very similar to what I need.
The problem I'm running into is that after the authentication flow runs into the "action" method of the custom Authenticator, an exception is thrown from the AuthenticationProcessor Class, which after inspection, comes from following check:
// org.keycloak.authentication.AuthenticationProcessor - line 876
if (authenticationSession.getAuthenticatedUser() == null) {
throw new AuthenticationFlowException(AuthenticationFlowError.UNKNOWN_USER);
}
after seeing this problem, my idea for trying solving it, was getting the user (already verified against the externl Identity Provider) from the keycloak store, and pushing it into the AuthenticationSession, like this:
// Connect against external Service Provider
// and asume "USER_ID" represents an already validated User
// AuthenticationFlowContext = afc is given as parameter
UserFederationManager ufm = afc.getSession().users(); // <-- PROBLEM
UserModel userFound = ufm.getUserById("USER_ID", afc.getRealm());
if (userFound != null) {
// get reference to the authSession
AuthenticationSessionModel asm = afc.getAuthenticationSession();
// set authenticated user on the session
asm.setAuthenticatedUser(userFound );
return true;
}
return false;
The problem with the above code, is that a Java NoSuchMethodExceptionError is thrown regarding the users() method of the org.keaycloak.models.KeycloackSession class. Like this:
11:26:32,628 ERROR [org.keycloak.services.error.KeycloakErrorHandler] (default task-14) Uncaught server error: java.lang.NoSuchMethodError: org.keycloak.models.KeycloakSession.users()Lorg/keycloak/models/UserFederationManager;
Any suggestion that you could make to help me solve this would be greatly appreciated!

It seems the problem was that I was using an org.keycloak.models.UserFederationManager instance, instead of an org.keycloak.models.UserProvider instance. The UserFederationManager implements the UserProvider, and it seems the more general type works better than the more specific type under the injection mechanism this keycloak is using
// UserFederationManager ufm = afc.getSession().users(); // <-- PROBLEM
// UserProvider ufm = afc.getSession().users(); // <-- WORKS
Even though it works now, both of your suggestions are valid because my build version is indeed diferent that the one on the runtime, I'll solve that to avoid further Bugs.
Thanks your input Guys!

As Henry stated, it's likely to be a version conflict. I had a similar problem which was solved with this thread's help. It suggests you downgrade some dependencies version, but in my case, we solved it changing back our server to Tomcat.

How to fix "org.apache.shiro.UnavailableSecurityManagerException" error with "SecurityUtils.getSubject()"

I try to read data from web-server, which situated at some URL.
In our company I use e-Commerce API, which works with the data from web-server.
To retrieve the data at first I need to make pool of the data from web-server.
To make the pool of data I need to configure connection.
One part from step "I need to configure connection" is function getSession(), which uses the Shiro api(org.apache.shiro.SecurityUtils)
so every time when I try to make connection with web-server and use the data from the web-server I become an Exception "Exception in thread "main" org.apache.shiro.UnavailableSecurityManagerException: No SecurityManager accessible to the calling code, either bound to the org.apache.shiro.util.ThreadContext or as a vm static singleton. This is an invalid application configuration."
Before writing this question I tried to look at logs and read about classes and problem, which describe there.
This all runs on Windows 10, Java 8, Payara Server(Glassfish), with EJBAPI and some e-Commerce API.
Import that I use
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.session.InvalidSessionException;
import org.apache.shiro.session.Session;
import org.apache.shiro.subject.Subject;
at
ContentConfiguration conf = new ContentConfiguration(
getSessionId(),
Constant.ENTITYMODELL,
Constant.EMPTY,
context);
protected static Session getSession()
{
Subject subject = SecurityUtils.getSubject();
if(subject.isAuthenticated())
return subject.getSession();
else
return null;
}
Error Message
Exception in thread "main" org.apache.shiro.UnavailableSecurityManagerException: No SecurityManager accessible to the calling code, either bound to the org.apache.shiro.util.ThreadContext or as a vm static singleton. This is an invalid application configuration.

I want to get answer which represent situation in my company, but a lot of principes, which i will to describe connect with common proplem in Shiro hub.
1.My problem connect with getSessionId() enter image description here
2.getSessionId() it's a function from company API. In this function i call org.apache.shiro.SecurityUtils.getSubject() enter
link description here
At this moment I thought about exception Message No SecurityManager accessible to the calling code.... Than I look at Shiro documentation here enter link description here. There i found, that every time when i use Aplication, which use authentication and autorisation i need to configure "SecurityManager" with "Realm" object.
4.It is a small instruction and detailed instruction present at shiro site enter link description here

Couchbase failure to find bucket local instance

Following the implementation guide from Spring on creating CouchbaseConfig by extending AbstractCouchbaseConfiguration.
Problem #1
My local Couch instance exists on "http://localhost:5984/" At application runtime the default port always results in the value "11210" which ultimatly results in connectivity failure.
Solution
To resolve this issue I am overriding the implementation which creates CouchbaseClient within my CouchbaseConfig component (Code snippet below)
public CouchbaseClient couchbaseClient() throws Exception {
CouchbaseClient client = null;
URI local=new URI("http://127.0.0.1:5984");
List<URI> baseURIs=new ArrayList<URI>();
baseURIs.add(local);
client = new CouchbaseClient(baseURIs, bucketValue, "");
......
I am still not able to locate the bucket I have setup in my local couch instance
http-bio-8080-exec-25] INFO 18:18:14,172 SLF4JLogger.log(87) - Could not fetch config from http seed nodes.
com.couchbase.client.vbucket.ConfigurationException: Configuration for bucket "bucketValue" was not found in server list ([http://127.0.0.1:5984]).
at com.couchbase.client.vbucket.ConfigurationProviderHTTP.readPools(ConfigurationProviderHTTP.java:271)
at com.couchbase.client.vbucket.ConfigurationProviderHTTP.getBucketConfiguration(ConfigurationProviderHTTP.java:143)
at com.couchbase.client.vbucket.provider.BucketConfigurationProvider.bootstrapHttp(BucketConfigurationProvider.java:351)
Any information on how to resolve this would be greatly appreciated.

So, I think what you have done here is confused Couchbase and CouchDb - they are entirely different platforms, even though they have confusingly-similar names.
You need to install a local instance of Couchbase if that is what you are trying to do, and get rid of Couchdb.

Verification failure while using openid4java for 'login with google'

I am using openid4java library for implementing the 'login with google' functionality in a spring-mvc application.
It works fine on my local tomcat server but on the remote server it has suddenly stopped working. It was working fine before there too.
After doing some logging in catalina.out I found that the verification of the response fails after google redirects to the return url
VerificationResult verification = openIdService.getConsumerManager().verify(
receivingURL.toString(),
response, discovered);
Identifier verified = verification.getVerifiedId(); //Null
The value of verified is null on the remote server. On local server its an uri
I am aware that while handling the response, ConsumerManager needs to be the same
instance used to place the authentication request.
The rest of the code is implemented as follows
There is an OpenIdController in which OpenIdService is Autowired.
The OpenIdServiceImpl implements OpenIdService and has the getConsumerManager method which returns the consumerManager instance.
In the construct of the OpenIdServiceImpl, an instance of ConsumerManager is created.
The actions that create the form for submission and handle the response are written in the
OpenIdController and access the consumerManager instance using the getConsumerManager method.
Edit:
I tried logging the Discovery information before the form submission and in the call back here it the output
Debugging OpenId: Discovered (before) OpenID2
OP-endpoint:https://www.google.com/accounts/o8/ud
ClaimedID:null
Delegate:null
Debugging OpenId: Discovered (after) OpenID2
OP-endpoint:https://www.google.com/accounts/o8/ud
ClaimedID:null
Delegate:nul
Am I doing anything wrong here ? But it works on local server!
Or something to do with tomcat configuration on the remote server ?
Any help is appreciated. I can post code if required.
Thanks.

I could resolve this problem by adding the following lines after creating an instance of ConsumerManager.
consumerManager.setAssociations(new InMemoryConsumerAssociationStore());
consumerManager.setNonceVerifier(new InMemoryNonceVerifier(5000));
consumerManager.setMinAssocSessEnc(AssociationSessionType.DH_SHA256);
I found it mentioned it in one of the comments to the SampleConsumer example here - http://code.google.com/p/openid4java/wiki/SampleConsumer
see response #3 from the bottom.
Haven't yet tried to figure out what it does, but hope its the right way to solve it :)
