Unable to create SSL context for SSO wallet for connecting to OracleDB

Question

I am trying to create SSL context for SSO wallet.

PoolDataSource poolDataSource = PoolDataSourceFactory.getPoolDataSource();
poolDataSource.setSSLContext(//call to create SSL instance);

Code for creating SSL context is:

TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance("PKIX");
KeyManagerFactory keyManagerFactory = KeyManagerFactory.getInstance("PKIX");
byte[] keyStoreData = //fetch keystore byte data
InputStream keyStoreInputStream = new ByteArrayInputStream(keyStoreData);
KeyStore keyStore = KeyStore.getInstance("SSO", new OraclePKIProvider()); //This line throws Exception. Line no. 102
keyStore.load(keyStoreInputStream, null);
keyManagerFactory.init(keyStore, null);
trustManagerFactory.init(keyStore);
SSLContext sslContext = SSLContext.getInstance("SSL");
sslContext.init(keyManagerFactory.getKeyManagers(), trustManagerFactory.getTrustManagers(), null);

But I am getting the following error:
