reactor.core.Exceptions$ReactiveException: javax.net.ssl.SSLHandshakeException: Unsupported curveId: 29

I have integrated the code in my product but it throwing error at this line and I'm using open jdk8. AccessToken accesstoken=clientSecretCredential.getToken(request).block();

Any reason why I'm getting this error. reactor.core.Exceptions$ReactiveException: javax.net.ssl.SSLHandshakeException: Unsupported curveId: 29

After multiple executions, I started getting error

@jianghaolu can you please take a look?

I have written the code like

    ClientSecretCredential clientSecretCredential = new ClientSecretCredentialBuilder()
            .clientId("Some id")
            .clientSecret("secret")
            .tenantId("tenentid")
            .build();

    TokenRequestContext request = new TokenRequestContext();
    System.out.println("444");
    request.addScopes("https://database.windows.net//.default");
    String token;
    AccessToken accesstoken=clientSecretCredential.getToken(request).block(Duration.ofMinutes(1));

    return accesstoken;

It's failing over AccessToken accesstoken=clientSecretCredential.getToken(request).block(Duration.ofMinutes(1));

While executing standalone program it's working but when I'm integrating this with my application same code failing

reactor.core.Exceptions$ReactiveException: java.net.SocketException: Connection reset

even I put some duration in the block method but it does not help.

Hi @ajaiswal595 Without knowing more details about your application it's difficult to tell what may be going on. If you can help answer the following questions I may be able to find out more what's going on: 1) Which version of azure-identity you are using? Our latest stable 1.0.8 uses HttpUrlConnection to authenticate and the preview 1.1.0-beta.5 uses Netty. They have different SSL implementations so using the other might fix your problem. 2) It could also be because of the exhaustion of the fork join pool. You can try adding .executorService(Executors.newCachedThreadPool()) to the builder to avoid using the fork join pool. 3) It could also be the conflict of a dependency. If you could share the classpath your application is running on, I can check if there might be a dependency that's not compatible with the azure identity library.

Here is the list of jars being used in my application. and azure identity is 1.0.7.

Hi @jianghaolu,

I have added here a list of dependencies in my Build Path. Could you please see it.

For this It could also be because of the exhaustion of the fork join pool. You can try adding .executorService(Executors.newCachedThreadPool()) to the builder to avoid using the fork join pool.

Can you provide a piece of logic I have to place instead of the one I have added?

It will be like

    ClientSecretCredential clientSecretCredential = new ClientSecretCredentialBuilder()
            .clientId("Some id")
            .clientSecret("secret")
            .tenantId("tenentid")
            .executorService(Executors.newCachedThreadPool())
            .build();

There is no such method executorService() applicable in ClientSecretCredential which takes input as Executors and return ClientSecretCredential.

I checked with 1.0.7 as well as 1.0.8

@ajaiswal595 Sorry I forgot to mention - you will need the preview version like 1.1.0-beta.6: https://repo1.maven.org/maven2/com/azure/azure-identity/1.1.0-beta.6/

Hi Even after using executerservice i'm getting error

What is causing these errors still unknown for me?

Can we get access token using Postman so I can write my custom code using httpclient and set it in datasource.

public static String getAccessToken() throws IOException {

    String result = "";

    HttpPost post = new HttpPost("https://login.microsoftonline.com/{{tenent_Id}}/oauth2/token");
    List<NameValuePair> urlParameters = new ArrayList<>();
    urlParameters.add(new BasicNameValuePair("grant_type", "client_credentials"));
    urlParameters.add(new BasicNameValuePair("client_id", "client_id"));
    urlParameters.add(new BasicNameValuePair("client_secret", "Jclient_secret"));
    urlParameters.add(new BasicNameValuePair("resource", "https://database.windows.net"));

    post.setEntity(new UrlEncodedFormEntity(urlParameters));

    try (CloseableHttpClient httpClient = HttpClients.createDefault();
         CloseableHttpResponse response = httpClient.execute(post)){

        result = EntityUtils.toString(response.getEntity());
    }

    ObjectNode node = new ObjectMapper().readValue(result, ObjectNode.class);

    System.out.println(result);

    if (node.has("access_token")) {
        result = node.get("access_token").toString();           
    }
    System.out.println(result);
    System.out.println(result.substring(1, result.length()-1));
    return result.substring(1, result.length()-1);

}

I'm able to get the token but it's gets expire, How would I get a refresh token or something that it never gets expired, as my application keeps sending data to the database forever.

You are using the client_credential flow, in this flow refresh_token isn't required. whenever your access token expire you can make another call to get the new access token. Refresh Token is given in the user interactive flows of OAuth, where you can use the refresh token for getting the new access token without user interaction once the access token expired.

@ajaiswal595 I've reached out to the msal team to inquire about the specific error you are getting here. But I'm almost certain this is not caused by the server but by the client. If you can write a small reproducible sample and share with us, it will be easier also for us to debug and come up with a fix.

Meanwhile if you want to know the actual on the wire, you can write a small sample and catch the traffic in Fiddler.

@jianghaolu thanks for all your support but I have achieved it using custom code even I'm not able to figure out why it was throwing error so I wrote custom code and its working for me.

    }

    @Override
    public void run() {

        String result = "";
        HttpPost post = new HttpPost(ENDPOINT+this.tenetId+"/oauth2/token");

        confirmTokenFlag=true;
        logger.info("set confirmTokenFlag true");

    }
}

And the caller will be like

SQLServerDataSource ds = new SQLServerDataSource();

        AzureServicePrincipleTokenManager azureServicePrincipleTokenManager = new AzureServicePrincipleTokenManager(ds,"your tenentID","your clientID","your secret");
        ScheduledExecutorService sches = Executors.newScheduledThreadPool(1);
        sches.scheduleWithFixedDelay(azureServicePrincipleTokenManager, 0, 45, TimeUnit.MINUTES);
        logger.info("----ExecuterService started the Runnable task");

        while (azureServicePrincipleTokenManager.getConfirmTokenFlag()!=true){

            ds.getAccessToken(); //I wonder If i leave while body balnk it never become true. so intentionally i'm calling ds.getAccessToken();
        }
            logger.info("----get the token after settingup  "+ds.getAccessToken());

I'm glad it works out for you in the end and thanks for sharing your code! Sorry I couldn't be more help. I'll forward your code to the msal folks to see if they can figure out why this code works with AAD but not theirs.

Seems like you have resolved the issue thus closing. This seems to be a standalone case at this time.

But if anyone else runs into this same issue and can provide a minimal reproducible sample, we would be happy to find the root cause.
