java: javax.net.ssl.SSLHandshakeException

Hello everyone,

I 've been trying to use the API, but I get the following error:

I have this issue while just trying to do the following:

ApiClient client = Config.defaultClient();
Configuration.setDefaultApiClient(client);
CoreV1Api apiInstance = new CoreV1Api();
        // get namespace list as a result
        V1NamespaceList v1NamespaceList = apiInstance.listNamespace(null, null, null, null, null, null, null, null, null);
        // add namespace names to a list
        return v1NamespaceList
                .getItems()
                .stream()
                .map(v1Namespace -> v1Namespace.getMetadata().getName())
                .collect(Collectors.toList());

I suspect the error lies on those lines:

ApiClient client = Config.defaultClient();
Configuration.setDefaultApiClient(client);

During my efforts, I have tried to use Java 8, Java 11 and Java 13 and nothing changed.

Any help would be very important.

Thank you!
