Creating an ssl connection to oracle db with Java

Question

I'm trying to connect to an Oracle DB using Java and SSL. For now I have the Java program on the server with the database.

I'm getting this error when I try to run it (full error in comment):

java.sql.SQLRecoverableException: IO Error: Inbound closed before receiving peer's close_notify: possible truncation attack?, connect lapse 15 ms., Authentication lapse 0 ms.

This is my java code:

public static void main(String[] args) {
        Security.addProvider(new oracle.security.pki.OraclePKIProvider());
        String url = "jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=tcps)(HOST=localhost)(PORT=2484))(CONNECT_DATA=(SERVICE_NAME=ORCL)))"; 
        Properties props = new Properties(); 
        props.setProperty("javax.net.ssl.trustStore", 
                "C:\\app\\Administrator\\virtual\\product\\12.2.0\\dbhome_1\\bin\\wallets\\Administrator\\cwallet.sso"); 
        props.setProperty("javax.net.ssl.trustStoreType","SSO"); 
        props.setProperty("javax.net.ssl.keyStore", 
                "C:\\app\\Administrator\\virtual\\product\\12.2.0\\dbhome_1\\bin\\wallets\\Administrator\\cwallet.sso"); 
        props.setProperty("javax.net.ssl.keyStoreType","SSO"); 
        try {
            Connection conn = DriverManager.getConnection(url, props);
        } catch (SQLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } 
    }

I added this to listener.ora and tnsnames.ora (I also tried with the sso file and just linking to the directory)

WALLET_LOCATION=(SOURCE=(METHOD=FILE) (METHOD_DATA=(DIRECTORY=C:\app\Administrator\virtual\product\12.2.0\dbhome_1\bin\wallets\Administrator\ewallet.p12 ))
SSL_CLIENT_AUTHENTICATION=TRUE

I also added this to java.security:

security.provider.11=oracle.security.pki.OraclePKIProvider

edit: I didn't realize the length limit on comments was so short. Here's the full error:

Can you make sure to have oraclepki.jar, osdt_core.jar and osdt_cert.jar in the classpath? You don't need to use keystore and truststore properties. Use oracle.net.wallet_location and oracle.net.ssl_server_dn_match=true. Check out the blog for more details.
