vpeddada opened a new issue, #20078: URL: https://github.com/apache/pulsar/issues/20078
### Search before asking - [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar. ### Version Java Client(Tried with 2.10.2 as well as 2.11.0)-->broker(2.11.0) Broker instance OS: Amazon Linux 2023 Java App running OS : Windows 10 ### Minimal reproduce step 1. Configure the Pulsar instance for mTLS authenticationa using Keystore. Then create the Pulsar client using the following sample code. ``` PulsarClient client = PulsarClient.builder() .serviceUrl("pulsar+ssl://broker.example.com:6651/") .useKeyStoreTls(true) .tlsTrustStorePath("/var/private/tls/client.truststore.jks") .tlsTrustStorePassword("clientpw") .allowTlsInsecureConnection(false) .enableTlsHostnameVerification(false) .authentication( "org.apache.pulsar.client.impl.auth.AuthenticationKeyStoreTls", "keyStoreType:JKS,keyStorePath:/var/private/tls/client.keystore.jks,keyStorePassword:clientpw") .build(); ``` 2. Provide incorrect keystore details or password details or incorrect configuration( Incorrect steps to create the keystore files or broker configuration). ### What did you expect to see? Proper exception messages should be returned with relevant causes of the exception. ### What did you see instead? For any type of issue with JKS files or password or with broker instance configuration only single exception will be returned. > org.apache.pulsar.client.api.PulsarClientException: java.util.concurrent.CompletionException: java.lang.NullPointerException{"previous":[{"attempt":0,"error":"java.util.concurrent.CompletionException: org.apache.pulsar.client.api.PulsarClientException: java.util.concurrent.CompletionException: java.lang.NullPointerException"},{"attempt":1,"error":"java.util.concurrent.CompletionException: org.apache.pulsar.client.api.PulsarClientException: java.util.concurrent.CompletionException: java.lang.NullPointerException"},{"attempt":2,"error":"java.util.concurrent.CompletionException: org.apache.pulsar.client.api.PulsarClientException: java.util.concurrent.CompletionException: java.lang.NullPointerException"},{"attempt":3,"error":"java.util.concurrent.CompletionException: org.apache.pulsar.client.api.PulsarClientException: java.util.concurrent.CompletionException: java.lang.NullPointerException"},{"attempt":4,"error":"java.util.concurrent.CompletionException: org.apache.pulsar.client.api .PulsarClientException: java.util.concurrent.CompletionException: java.lang.NullPointerException"},{"attempt":5,"error":"java.util.concurrent.CompletionException: org.apache.pulsar.client.api.PulsarClientException: java.util.concurrent.CompletionException: java.lang.NullPointerException"},{"attempt":6,"error":"java.util.concurrent.CompletionException: org.apache.pulsar.client.api.PulsarClientException: java.util.concurrent.CompletionException: java.lang.NullPointerException"},{"attempt":7,"error":"java.util.concurrent.CompletionException: org.apache.pulsar.client.api.PulsarClientException: java.util.concurrent.CompletionException: java.lang.NullPointerException"},{"attempt":8,"error":"java.util.concurrent.CompletionException: org.apache.pulsar.client.api.PulsarClientException: java.util.concurrent.CompletionException: java.lang.NullPointerException"}]}].. ### Anything else? _No response_ ### Are you willing to submit a PR? - [ ] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
